Nano-Optical Conveyor Belt, Part I: Theory
NANO LETTERS
2014; 14 (6): 2965-2970
Abstract
We propose a method for peristaltic transport of nanoparticles using the optical force field over a nanostructured surface. Nanostructures may be designed to produce strong near-field hot spots when illuminated. The hot spots function as optical traps, separately addressable by their resonant wavelengths and polarizations. By activating closely packed traps sequentially, nanoparticles may be handed off between adjacent traps in a peristaltic fashion. A linear repeating structure of three separately addressable traps forms a "nano-optical conveyor belt"; a unit cell with four separately addressable traps permits controlled peristaltic transport in the plane. Using specifically designed activation sequences allows particle sorting.

Nano-Optical Conveyor Belt, Part II: Demonstration of Handoff Between Near-Field Optical Traps
NANO LETTERS
2014; 14 (6): 2971-2976
Abstract
Optical tweezers have been widely used to manipulate biological and colloidal material, but the diffraction limit of far-field optics makes focused beams unsuitable for manipulating nanoscale objects with dimensions much smaller than the wavelength of light. While plasmonic structures have recently been successful in trapping nanoscale objects with high positioning accuracy, using such structures for manipulation over longer range has remained a significant challenge. In this work, we introduce a conveyor belt design based on a novel plasmonic structure, the resonant C-shaped engraving (CSE). We show how long-range manipulation is made possible by means of handoff between neighboring CSEs, and we present a simple technique for controlling handoff by rotating the polarization of laser illumination. We experimentally demonstrate handoff between a pair of CSEs for polystyrene spheres 200, 390, and 500 nm in diameter. We then extend this technique and demonstrate controlled particle transport down a 4.5 μm long "nano-optical conveyor belt."

Ultra-high resolution resonant C-shaped aperture nano-tip
OPTICS EXPRESS
2011; 19 (6): 5077-5085
Abstract
We report a new optical near-field transducer comprised of a metallic nano-antenna extending from the ridge of a C-shaped metallic nano-aperture. Finite-difference time domain simulations predict that the C-aperture nano-tip (CAN-Tip) provides high intensity (650x), high optical resolution (~?/60), and background-free near-field illumination at a wavelength of 980 nm. The CAN-Tip has an aperture resonance and tip antenna resonance which may be tuned independently, so the structure can be made resonant at ultraviolet wavelengths without being unduly small. This near-field optical resolution of 16.1 nm has been experimentally confirmed by employing the CAN-Tip as an NSOM probe.

Fast and accurate algorithm for the computation of complex linear canonical transforms
JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION
2010; 27 (9): 1896-1908
Abstract
A fast and accurate algorithm is developed for the numerical computation of the family of complex linear canonical transforms (CLCTs), which represent the input-output relationship of complex quadratic-phase systems. Allowing the linear canonical transform parameters to be complex numbers makes it possible to represent paraxial optical systems that involve complex parameters. These include lossy systems such as Gaussian apertures, Gaussian ducts, or complex graded-index media, as well as lossless thin lenses and sections of free space and any arbitrary combinations of them. Complex-ordered fractional Fourier transforms (CFRTs) are a special case of CLCTs, and therefore a fast and accurate algorithm to compute CFRTs is included as a special case of the presented algorithm. The algorithm is based on decomposition of an arbitrary CLCT matrix into real and complex chirp multiplications and Fourier transforms. The samples of the output are obtained from the samples of the input in approximately N log N time, where N is the number of input samples. A space-bandwidth product tracking formalism is developed to ensure that the number of samples is information-theoretically sufficient to reconstruct the continuous transform, but not unnecessarily redundant.

Fast and accurate computation of two-dimensional non-separable quadratic-phase integrals
JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION
2010; 27 (6): 1288-1302
Abstract
We report a fast and accurate algorithm for numerical computation of two-dimensional non-separable linear canonical transforms (2D-NS-LCTs). Also known as quadratic-phase integrals, this class of integral transforms represents a broad class of optical systems including Fresnel propagation in free space, propagation in graded-index media, passage through thin lenses, and arbitrary concatenations of any number of these, including anamorphic/astigmatic/non-orthogonal cases. The general two-dimensional non-separable case poses several challenges which do not exist in the one-dimensional case and the separable two-dimensional case. The algorithm takes approximately N log N time, where N is the two-dimensional space-bandwidth product of the signal. Our method properly tracks and controls the space-bandwidth products in two dimensions, in order to achieve information theoretically sufficient, but not wastefully redundant, sampling required for the reconstruction of the underlying continuous functions at any stage of the algorithm. Additionally, we provide an alternative definition of general 2D-NS-LCTs that shows its kernel explicitly in terms of its ten parameters, and relate these parameters bidirectionally to conventional ABCD matrix parameters.

Improved focused ion beam fabrication of near-field apertures using a silicon nitride membrane
OPTICS LETTERS
2008; 33 (23): 2827-2829
Abstract
We report an improved fabrication method for C-shaped near-field apertures resonant in the near-IR regime. The apertures are created in a metal layer on a silicon nitride membrane using a focused ion beam and a through membrane milling technique that avoids two problems with fabricating very small apertures: gallium contamination and edge rounding. Finite-difference time-domain simulations predict a 63x more intense near field with a 2.2x smaller spot versus conventionally milled apertures. We verify the position of the simulated resonance peaks with experimental far-field transmission measurements where we also find an increase of 8.8x in intensity. Our method has applications to many other plasmonic devices including bow-tie and fractal apertures, periodic arrays, and gratings.

Three-dimensional optical disk data storage via the localized alteration of a format hologram
APPLIED OPTICS
2008; 47 (14): 2696-2707
Abstract
Three-dimensional optical data storage is demonstrated in an initially homogenous volume by first recording a reflection grating in a holographic photopolymer. This causes the entire volume to be weakly reflecting to a confocal read/write head. Superposition of two or three such gratings with slightly different k-vectors creates a track and layer structure that specialized servo detection optics can use to lock the focus to these deeply-buried tracks. Writing is accomplished by locally modifying the reflectivity of the preexisting hologram. This modification can take the form of ablation, inelastic deformation via heating at the focus, or erasure via linear or two-photon continued polymerization in the previously unexposed fringes of the hologram. Storage by each method is demonstrated with up to eight data layers separated by as little as 12 microns.

High transmission through ridge nano-apertures on vertical-cavity surface-emitting lasers
OPTICS EXPRESS
2007; 15 (16): 10427-10438
Abstract
We report high-intensity nano-aperture Vertical-Cavity Surface- Emitting Lasers (VCSELs) with sub-100nm near-field spots using ridge apertures. Power transmission efficiency through different ridge apertures, including bowtie, C, H and I-shaped apertures on VCSELs were studied. Significantly higher transmission efficiencies were obtained from the ridge apertures than those from conventional square apertures. Mechanisms for high transmission through the ridge apertures are explained through simulation and waveguide theory. A new quadruple-ridge aperture is proposed and designed via simulation. With the high-intensity and small spot size, VCSELs using these ridge nano-apertures are very promising means to realize applications such as ultrahigh-density near-field optical data storage and ultrahigh-resolution near-field imaging etc.

High-intensity bowtie-shaped nano-aperture vertical-cavity surface-emitting laser for near-field optics
OPTICS LETTERS
2007; 32 (14): 1995-1997
Abstract
We report a high-intensity nano-aperture vertical-cavity surface-emitting laser (VCSEL) utilizing a bowtie-shaped aperture. A maximum power of 188 microW is achieved from a 180 nm bowtie aperture at a wavelength of 970 nm. The near-field full width at half-maximum intensity spot size 20 nm away from the bowtie aperture is 64 nm x 66 nm from simulation, and the peak near-field intensity is estimated to be as high as 47 mW/microm(2). This intensity is high enough to realize near-field optical recording, and the small spot size corresponds to storage densities up to 150 Gbits/in(2). The bowtie-aperture VCSEL also enables other applications, such as compact high-intensity probes for ultrahigh-resolution near-field imaging and single molecule fluorescence and spectroscopy.

Pulsed-interleaved excitation FRET measurements on single duplex DNA molecules inside C-shaped nanoapertures
NANO LETTERS
2007; 7 (6): 1749-1756
Abstract
Single-molecule fluorescence resonant energy transfer (FRET) is a widely accepted method for determining the spatial separation between molecules. In combination with pulsed interleaved excitation (PIE), additional information about the stoichiometry of molecular interactions is obtained. PIE-FRET, however, as implemented with standard confocal optics, requires the dilution of the sample to biologically low concentrations. Here, we show that PIE-FRET measurements inside nanometer-sized apertures yield meaningful biochemical data at 1000 x higher concentrations.

Low-loss subwavelength metal C-aperture waveguide
OPTICS LETTERS
2006; 31 (24): 3606-3608
Abstract
We present a design of a linear optical waveguide that utilizes a C-shaped metallic nano-aperture that efficiently transports light while maintaining a spot size of lambda/10. The performance of a C-aperture waveguide is superior to both a regular ridge waveguide and other surface plasmon based metal nano-optical waveguides. The energy transport mechanisms are explained by the coupling of an aperture surface resonance and the thickness resonances inside the guide channel. Finite-difference time-domain simulations of gold C-aperture waveguides are performed for a 1.5 microm wavelength incident plane wave. The 1/e decay length in power transmission is predicted to be approximately 2.5 microm. The total power throughput is 1.66 for the 2.55 microm long guide, with an intensity 6 times that of the incident wave at a distance 120 nm from the exit plane, having a spot size of 150 nm.

Media tilt tolerance of bit-based and page-based holographic storage systems
OPTICS LETTERS
2006; 31 (10): 1513-1515
Abstract
Tilt tolerance of media is compared for bit-based and page-based holographic storage systems having an equal diffraction efficiency per bit detector, dynamic range of the medium, and surface recording density. We have formalized the diffraction efficiency degradation caused by aberrations of a reconstructing reference beam induced by tilt of the medium, using a coupled wave theory in the Fourier domain. The bit-based holographic storage system has a larger media tilt tolerance compared with a page-based system with relatively large page size.

Laser ablation of silicon in water with nanosecond and femtosecond pulses
OPTICS LETTERS
2005; 30 (13): 1740-1742
Abstract
We describe laser ablation of Si under water by 5 ns, 355 nm and 100 fs, 800 nm pulses. Compared to that in air, an approximately twofold improvement in the ablation rate is found in water for femtosecond and nanosecond pulses. For higher laser irradiances, the plasma that forms at the water-air interface hampers further improvement of the ablation rate. We investigated the enhanced ablation process in water and found that the cavity-confinement geometry that increases the laser energy coupling to the target and allows more energy to be transferred to the cavity sidewalls plays an important role in the escalated material removal process. In addition, we show that the water layer that effectively reduces the oxidation and redeposition of the ablated debris is also responsible for improvements in the ablation process.

Microholographic multilayer optical disk data storage
APPLIED OPTICS
2005; 44 (16): 3197-3207
Abstract
Micrometer-sized reflection holograms can be written into a rapidly rotating homogeneous photopolymer disk at the focus of a high-numerical-aperture beam and its retroreflection to implement high-capacity multilayer digital data storage. This retroreflection is generated by an optical system with positive unity magnification to ensure passive alignment of the counterpropagating beam. Analysis reveals that the storage capacity and transfer rate of this bit-based holographic storage system compare favorably with traditional page-based systems but at a fraction of the system complexity and cost. The analysis is experimentally validated at 532 nm by writing and reading 12 layers of microholograms in a 125-microm photopolymer disk continuously rotating at 3600 rpm. The experimental results predict a capacity limit of 140 Gbytes in a millimeter-thick disk or over 1 Tbyte with the wavelength and numerical aperture of Blu-Ray.

Fractal extensions of near-field aperture shapes for enhanced transmission and resolution
OPTICS EXPRESS
2005; 13 (2): 636-647
Abstract
Families of fractals are investigated as near-field aperture shapes. They are shown to have multiple transmission resonances associated with their multiple length scales. The higher iterations exhibit enhanced transmission, and spatial resolution exceeding the first order. Near-field enhancements of greater than 400 times the incident intensity and resolutions of better than ?/20 have been shown with apertures modeled after third iteration prefractals. Enhancements as large as 1011 have been shown, when compared with conventional square apertures that produce the same spot size. The effects of the complex permittivity values of the metal film are also addressed.

High-transfer-rate high-capacity holographic disk data-storage system
APPLIED OPTICS
2004; 43 (25): 4902-4914
Abstract
We describe the design and implementation of a high-data-rate high-capacity digital holographic storage disk system. Various system design trade-offs that affect density and data-rate performance are described and analyzed. In the demonstration system that we describe, high-density holographic recording is achieved by use of high-resolution short-focal-length optics and correlation shift multiplexing in photopolymer disk media. Holographic channel decoding at a 1-Gbit/s data rate is performed by custom-built electronic hardware. A benchmark sustained optical data-transfer rate of 10 Gbits/s has been successfully demonstrated.

Ultrahigh light transmission through a C-shaped nanoaperture
OPTICS LETTERS
2003; 28 (15): 1320-1322
Abstract
Optical resolution beyond the diffraction limit can be achieved by use of a metallic nanoaperture in a near-field optical system. Conventional nanoapertures have very low power throughput. Using a numerical finite-difference time domain method, we discovered a unique C-shaped aperture that provides approximately 3 orders of magnitude more power throughput than a conventional square aperture with a similar near-field spot size of approximately 0.1 lambda. Microwave experiments at 6 GHz quantitatively confirmed the simulated transmission enhancement. The high transmission of the C-aperture--or one of the related shapes--is linked to both a propagation mode in the aperture and local surface plasmons.

Light-induced absorption of cerium-doped lead barium niobate crystals
OPTICS LETTERS
1998; 23 (20): 1618-1620
Abstract
Tetragonal lead barium niobate (Pb(1-x)Ba(x)Nb(2)O(6);1-x<0.63) crystals are promising photorefractive materials for applications such as holographic data storage. Measurements of light-induced absorption in Ce-doped lead barium niobate (Pb(0.5)Ba(0.5) Nb(2)O(6)) were performed. The induced absorption that was due to the presence of shallow traps was as large as 0.3cm(-1) at 633 nm and exhibited saturation behavior at green-pump intensity greater than 2W/cm(2) . The temporal profile of the dark decay was a double exponential, and the activation energies of the slow- and the fast-decaying components were determined to be 0.16 and 0.3 eV, respectively.

Two-photon apodization in lithium niobate
OPTICS LETTERS
1998; 23 (17): 1399-1401
Abstract
We demonstrate a novel apodization technique for holographic data storage using two-photon recording in stoichiometric lithium niobate. The gating light-intensity profile is used to achieve grating apodization inside the bulk of the crystal during recording in the transmission geometry. Experimental Bragg-selectivity curves and theoretical fits indicate a >20-dB drop in multiplexing cross talk.

Abstract
We demonstrate a one-color one-beam pumping method for a three-dimensional two-step excitation fluorescent display with Er(3+) -doped ZBLAN glass. A localized green fluorescent spot is obtained by use of a focused pump-light beam at 979 nm. The quantum efficiency of the two-step excitation fluorescence is investigated in a time-dependent analysis and an experiment with a pulsed pump light.

Photorefractive materials for nonvolatile volume holographic data storage
Science (New York, N.Y.)
1998; 282 (5391): 1089-94
Abstract
Optically gated recording and nonvolatile readout in a digital volume holographic data storage system that uses a pair of mutually incoherent light sources during recording and only one for readout were demonstrated recently. This approach used stoichiometric lithium niobate, which after post-growth processing gave rise to an at least two orders of magnitude improvement in sensitivity over the best materials reported previously. It is also shown that by adding certain dopants (iron and manganese) to near-stoichiometric lithium niobate, the dark storage time and gating efficiency can be increased compared with previous work. The underlying physical mechanisms of gated recording and the effectiveness of the gating process responsible for this manifold improved performance are discussed, and bipolarons and small polarons are identified as the responsible photorefractive species.

Two-photon holographic recording in aluminosilicate glass containing silver particles
OPTICS LETTERS
1997; 22 (13): 967-969
Abstract
Recording of holographic gratings by 532-nm laser pulses in photochromic bulk aluminosilicate glass containing silver particles is demonstrated. A diffraction efficiency of 1.5% is achieved for readout at the same wavelength. The speed of grating formation as a function of pulse energy suggests that two-photon excitation is responsible for the recording. The light causes bleaching of an absorption peak near 417nm, which corresponds to the excitation of surface plasmons on the silver, and broad darkening throughout the visible to the near infrared. A likely mechanism for the photochromic effect is discussed.

Polymer films doped with 2-(5, 5-dimethyl-3-styryl-cyclohex-2-enylidene)-malononitrile chromophore and various sensitizers have been prepared and characterized. The material exhibits high sensitivity in the red region (S=0.26 cm(2)/J at lambda=633 nm), a large dynamic range (Dn=-0.05) , and large transient two-beam coupling gain (G=110 cm(-1)) . Self-diffraction effects, such as energy and phase coupling, and photoinduced scattering are studied.

Digital quasi-phase-matched two-color nonvolatile holographic storage
APPLIED OPTICS
1997; 36 (14): 3090-3106
Abstract
Unwanted erasure during readout of holographic data can be reduced or eliminated by use of a different wavelength for reading than that which was used for writing. To prevent distortion and Bragg mismatch that would be unacceptable for digital data storage, one can format data to account for the wavelength difference. Techniques to format data and the results of this formatting are presented. Varying the formatting parameters is investigated to optimize diffraction efficiency.

Observation and thermal fixing of holographic gratings in lead barium niobate crystal
OPTICS LETTERS
1997; 22 (3): 187-189
Abstract
We report what we believe to be the first observation of photorefractive gratings in lead barium niobate (Pb(1-x)Ba (x)Nb(2)O>( 6) ; PBN). A diffraction efficiency of 9% and a beam-coupling coefficient of 9 cm(-1) are obtained. After thermal fixing a grating of 0.5% is revealed at room temperature. We can improve this diffraction efficiency by optimizing fixing temperature, timing, and material parameters.

Digital holographic storage system incorporating thermal fixing in lithium niobate
OPTICS LETTERS
1996; 21 (19): 1615-1617
Abstract
We describe a digital holographic data storage system that uses in situ thermal fixing to achieve nonvolatile readout. The system was used to store and fix 530 holograms representing 1.7 MB of digital data. The system demonstrates that fixing by heating after recording gives adequate performance for multiplex holography in the perpendicular recording geometry. The postrecording heating procedure is preferred over high-temperature recording in the perpendicular geometry to achieve Bragg matching for the entire signal angular bandwidth.

Signal detection for page-access optical memories with intersymbol interference
APPLIED OPTICS
1996; 35 (14): 2431-2438
Abstract
We propose a technique for data detection in a two-dimensional page-access optical memory. The technique combines sequence detection by the use of the Viterbi algorithm with decision feedback to improve the bit-error-rate performance in a system corrupted by intersymbol interference. It has an advantage in that it can be operated on a row-by-row basis as data are output from the optical detector. Use of the proposed scheme might ease the design tolerances of the optical components or permit the use of large data pages.

CODED-WAVELENGTH MULTIPLEX VOLUME HOLOGRAPHY
OPTICS LETTERS
1995; 20 (18): 1916-1918
Abstract
We introduce the technique of coded-wavelength multiplex holography. We encode each wavelength with a discrete angular spectrum of plane waves, so that the total number of multiplexed holographic pages equals the number of wavelengths multiplied by the number of discrete wave vectors at each wavelength. Encoding with different propagation angles further permits one to utilize the properties of grating degeneracy to assemble an image from a mosaic of smaller images and to multiplex such images at different wavelengths.

Abstract
We describe an encrypted holographic data-storage system that combines orthogonal-phase-code multiplexing with a random-phase key. The system offers the security advantages of random-phase coding but retains the low cross-talk performance and the minimum code storage requirements typical in an orthogonal-phase-code-multiplexing system.

WAVELENGTH SELECTION FOR TRUE-COLOR HOLOGRAPHY
APPLIED OPTICS
1994; 33 (29): 6811-6817
Abstract
We discuss wavelength selection for true-color holography by investigating the sampling nature of the holographic process. During holographic recording the chosen wavelengths point sample the surfacereflectance functions of the objects in a scene. To understand the effect of this sampling on color perception, we study the tristimulus values of points in the reconstructed hologram. The sampling results in the holographic process being mathematically equivalent to integral approximations for the tristimulus integrals. By selecting efficient approximations, we infer wavelengths to use in color holography. Our analysis not only suggests wavelengths for the usual three-color holography but also suggests the use of four or more wavelengths to improve color reproduction in holography.

TRAPPING THE GRATING ENVELOPE IN BULK PHOTOREFRACTIVE MEDIA
OPTICS LETTERS
1994; 19 (18): 1415-1417
Abstract
We introduce the concept of traveling grating envelopes to study the erasure dynamics in bulk photorefractive media. This new technique provides considerable physical insight into the observed photorefractive transients. We propose and demonstrate experimentally, in a Ce-doped SBN:60 crystal, two novel ways of extending the grating lifetime by trapping the grating envelope inside the medium. The incident beam ratio and the readout geometry have the largest effect on how long the grating can be read out.

EFFECT OF APPLIED FIELDS ON THE BRAGG CONDITION AND THE DIFFRACTION EFFICIENCY IN PHOTOREFRACTIVE CRYSTALS
OPTICS LETTERS

Abstract
We explore theoretically and experimentally how application of an electric field to a photorefractive crystal affects the recording and the readout of holograms. We consider, for the first time to our knowledge, the effects of fringe bending caused by nonlinear two-wave mixing on the change in Bragg condition and diffraction efficiency as a function of the applied electric field. Practical performance limitations for holographic data storage and image amplification are discussed.

SUBMICROMETER DEFECT DETECTION IN PERIODIC STRUCTURES BY PHOTOREFRACTIVE HOLOGRAPHY - SYSTEM-DESIGN AND PERFORMANCE
APPLIED OPTICS
1994; 33 (5): 744-757
Abstract
We have built an adaptive system capable of detecting submicrometer defects in periodic structures by using real-time holography in photorefractive crystals. We summarize the design and optimization of the defect-enhancement system. We present representative results of 0.2- to 0.5-µm diameter defect detection on two different periodic substrates: chrome-on-glass masks and patterned silicon wafers. On patterned silicon we detect 94% of the 0.5-µm diameter defects with three false positives, while inspecting an area greater than 1 mm(2) in 20 s or less. The throughput on the glass masks is somewhat less. To the best of our knowledge, these defects have an area 100 times smaller than those previously detected with any real-time holographic technique.

LIMITATIONS OF PHASE-CONJUGATE REPLAY IN VOLUME-HOLOGRAPHIC PHASE-DISTURBING MEDIA
OPTICS LETTERS
1993; 18 (9): 741-743
Abstract
We examine the consequences of permanent phase distortions on the replay of transmission volume holograms with a phase-conjugated reference wave. In the absence of Bragg degeneracies and significant Bragg mismatch, for negligible dispersion in the spatial frequency response and for negligible variation in obliquity, phase-conjugated reference waves compensate for the effects of phase distortions and permit cross-talk-free multiplexing by using orthogonal reference waves. Spatial frequency dispersion, however, is a source of image distortion and cross talk.

DISTORTION-FREE MULTIPLEXED HOLOGRAPHY IN STRIATED PHOTOREFRACTIVE MEDIA
APPLIED OPTICS
1993; 32 (11): 1973-1982
Abstract
Growth-induced striations in photorefractive media constitute phase gratings that scatter transmitted light and therefore degrade the quality of reconstructed images in holographic applications. A simple angular multiplexed holographic memory arrangement in a striated strontium barium niobate sample is considered. For forward-propagating reconstruction the striations distort the readout images and introduce ghost images. For counterpropagating readout, inhomogeneous image reconstruction and interimage cross talk can occur. We investigate these effects experimentally for different reconstruction methods and demonstrate the cross talk and the ghost images with a simple model based on coupled-wave theory. Readout with a counterpropagating plane wave eliminates the ghost images and the distortions but suffers degradation from cross talk and inhomogeneous image intensity. Only reconstruction with a phase conjugate of the transmitted reference beam eliminates cross talk and distortions. The model indicates that negligible material dispersion is a necessary requirement for high-quality phaseconjugation readout.

ALLEVIATION OF IMAGE DISTORTION DUE TO STRIATIONS IN A PHOTOREFRACTIVE MEDIUM BY USING A PHASE-CONJUGATED REFERENCE WAVE
OPTICS LETTERS
1992; 17 (16): 1149-1151
Abstract
Growth-induced striations in photorefractive media scatter transmitted light, degrading their performance in holographic applications. We model this phenomenon by considering the striations to be a permanent hologram within a medium and compare it with experimental results in a striated strontium barium niobate crystal. We show that the construction of the phase-conjugate signal beam by a phase conjugate of the transmitted reference beam alleviates the effects of distortions that are due to striations.

SUBMICROMETER DEFECT ENHANCEMENT IN PERIODIC STRUCTURES BY USING PHOTOREFRACTIVE HOLOGRAPHY
OPTICS LETTERS
1992; 17 (15): 1087-1089
Abstract
We present a defect-enhancement system capable of detecting submicrometer defects on opaque periodic structures using real-time holography in photorefractive crystals. We detect 0.5-microm defects with ~90% success rate and 0.3-microm defects with >85% success rate while inspecting an area greater than 1 mm(2) in real time. To our knowledge, these defects have an area 100 times smaller than those previously detected with any real-time holographic technique.

ANALYSIS AND DESIGN OF AN ANAMORPHIC OPTICAL PROCESSOR FOR SPECKLE METROLOGY AND VELOCIMETRY
APPLIED OPTICS
1992; 31 (10): 1646-1659
Abstract
Two-dimensional velocity or displacement fields that are recorded as double-exposure speckle patterns may be measured with an anamorphic optical processor. The anamorphic optical processor measures one component of the velocity or displacement throughout a linear region of the double-exposure speckle pattern. The signal in the output plane of such a processor is a fringe pattern. An analysis to predict fringe modulation based on Fourier optics and the statistics of speckle patterns is developed. The analysis specifies the effects of both the speckle-recording optics and the anamorphic optical processor on the fringe modulation. The observed loss of modulation when the velocity or displacement component perpendicular to the measured component is increased is also described. Measurements of fringe modulations that are produced by anamorphic optical processors with and without increased tolerance to the perpendicular velocity component are compared to results of the analysis. Fringe modulation versus relative exposure in the double-exposure speckle pattern are also measured and compared to the results of this analysis. An anamorphic processor that reduces the time for digital processing of the fringe patterns by a factor of N (typically 128, 256, or 512) relative to the two-dimensional Fourier transform optical processor (with identical spatial resolution) is demonstrated.

TEMPERATURE, INTENSITY, AND FIELD-DEPENDENCE OF THE ABSORPTION-COEFFICIENT OF BI12SIO20
OPTICS LETTERS
1990; 15 (9): 455-457
Abstract
Department of Applied Physics, Stanford University, Stanford, California 94305We report the observation of incident intensity and applied-field-induced increases in the absorption coefficient of Bi(12)SiO(20) at 514.5 nm. Absorption changes as large as 50% have been observed, but 10% is more typical. The main effect is thermal shifting of the absorption edge caused by ohmic heating from the photocurrent: Deltaalpha(T) = 0.0083 cm(-1) K(-1). In addition, there is a small absorption change proportional to the intensity alone that is approximately given by Deltaalpha(I) = 0.03 ln(I). We also report a linear decrease in the photoconductivity with temperature for T in the range 295-330 K.

PHOTOREFRACTIVE INTEGRATED-OPTICAL SWITCH ARRAYS IN LINBO3
OPTICS LETTERS
1990; 15 (1): 30-32
Abstract
A new optical switch design is reported that consists of two sets of parallel channel waveguides intersecting at right angles. Arrays based on Ti:LiNbO(3) technology, with waveguide intersections iron doped to provide photorefractive sensitivity, have been fabricated. Interfering guided beams are used to write index gratings at the waveguide intersections, which in turn diffract a portion of an incident signal beam into the crossing waveguide. Arrays ranging from 15 x 15 up to 50 x 50 waveguides are constructed in an active area of 5 mm x 5 mm. Diffraction efficiency and writing-time measurements are reported along with a proposal for a practical architecture.

2-WAVELENGTH PHOTOREFRACTIVE DYNAMIC OPTICAL INTERCONNECT
OPTICS LETTERS
1989; 14 (21): 1174-1176
Abstract
A novel architecture for a reconfigurable optical routing switch using photorefractive crystals with nondestructive readout is presented. This design reduces the order of complexity from n(2) to n for a general two-wavelength n x n holographic interconnection network. The packing capacity of the network is discussed and is calculated to be of the order of 1000 x 1000 for an ideal volume holographic recording material. In practice, we show that the actual value is constrained by the number of gratings that can be multiplexed in a single photorefractive crystal. A 2 x 3 switch is demonstrated by using a Bi(12)GeO(20) crystal with 514-nm writing beams and 633-nm signal (readout) beams.

OPTICAL-SURFACE INSPECTION USING REAL-TIME FOURIER-TRANSFORM HOLOGRAPHY IN PHOTOREFRACTIVES
APPLIED OPTICS
1988; 27 (21): 4497-4503
Abstract
We present real-time optical preprocessor intended to enhance small defects in a smooth surface. The heart of the system is a photorefractive Bi(12)SiO(20) phase-conjugate mirror which reflects only the low intensity features of the object's optical Fourier transform. By adjusting the beam ratios so that only the low intensity, high spatial frequency image components are phase conjugated and inverse transformed, an image consisting of just the defects is produced. To our knowledge, this is the first use of this technique on opaque and nonperiodic objects. We present experimental data showing enhancement of defects as small as 0.14 microm.

PHOTOREFRACTIVE HOLOGRAPHIC RECORDING IN STRONTIUM BARIUM NIOBATE FIBERS
OPTICS LETTERS
1988; 13 (10): 877-879
Abstract
We describe what are to our knowledge the first photorefractive holographic recordings in a fiber. A plane-wave reference and an image-carrying object beam are incident upon the fiber in a reflection geometry. We report results on the angular sensitivity of the recordings, the image quality, and readout efficiency as a function of the reference-wave input angle when the object wave propagates along the bore of the fiber. These experiments are carried out for two relatively short, 4- and 8-mm, multimode 1-mm-diameter fibers. The results suggest that an array of fibers might favorably replace bulk materials for certain computer and signal-processing applications.

ENHANCED NONDESTRUCTIVE HOLOGRAPHIC READOUT IN STRONTIUM BARIUM NIOBATE
OPTICS LETTERS
1988; 13 (10): 880-883
Abstract
We describe a novel procedure for obtaining enhanced nondestructive holographic readout in SBN, where the key new ingredient is utilization of degrees of freedom in polarization of the reconstruction beam. The effect also involves spatial frequency and the applied voltage during both the recording and the reconstruction. The reconstructed beam first drops in intensity but subsequently grows in strength above the starting value, approaching 100% efficiency in some cases. More than 6 h of continuous readout has been achieved, with efficiency remaining strong enough to give more than 10(9) 10-microsec readouts with signal-to-noise ratios exceeding 20 dB.

SYNTHESIS OF A HOLOGRAPHIC IMAGE VELOCITY FILTER USING THE NONLINEAR PHOTOREFRACTIVE EFFECT

1988; 27 (14): 2887-2894
Abstract
We demonstrate a technique by which components of an image moving with a given speed and direction may be selectively enhanced. By using the strong grating velocity sensitivity of the nonlinear photorefractive response, we show that a BSO crystal used in a schlieren imaging system may be used as a real-time velocity filter. The velocity selectivity, tunability and resolution constraints of this system are discussed in detail.

REAL-TIME PHOTOREFRACTIVE RECORDING AND OPTICAL-PROCESSING FOR SPECKLE VELOCIMETRY
OPTICS LETTERS
1988; 13 (5): 348-350
Abstract
A photorefractive crystal (Bi(12)GeO(20)) is used to record double-exposure speckle patterns produced by Q-switched laser pulses in real-time speckle metrology and velocimetry applications. The speckle pattern displacements are immediately measured with an optical processor of the type used for measuring speckle displacements recorded on photographic film. Operation of the optical processor is described and compared with the case of film recording. Observed spatial and temporal recording properties of the crystal in this imaging configuration are discussed and compared with published results for single-frequency grating recording in photorefractives. The system is applied to measuring velocities of a moving solid object.

COMPUTER DISPLAY OF RECONSTRUCTED 3-D SCALAR DATA
APPLIED OPTICS
1988; 27 (2): 395-404
Abstract
This paper addresses the problem of visualizing 3-D scalar data, initially represented as an ordered set of digital images stacked parallel to each other. An observer's ability to perceive the geometry of the structures in these data fields depends on the methods of reconstructing and displaying 3-D representations. We describe three computer-based visualization methods that share the common goal of displaying the interior structures of 3-D data, and we present the results of applying these methods to a set of fluid-flow data. Interactive peeling of smooth opaque contour surfaces is the best of the three methods: it gives excellent perception cues.

DESIGN CONSIDERATIONS FOR HOLOGRAPHIC OPTICAL INTERCONNECTS
APPLIED OPTICS
1987; 26 (18): 3947-3953
Abstract
The geometrical design characteristics of multiple-image holograms are evaluated. A figure of merit expressing these characteristics as a function of the hologram diameter and the distance between the hologram and the image plane is developed. This value is then used to compare two designs which are capable of forming several hundred interconnections. The results indicate that these connections can be formed between points on the substrate separated by 2-3 cm provided that the holograms are separated from the substrate plane by 0.5-1 cm. Each hologram design is experimentally demonstrated in bleached photographic emulsions.

SODIUM PHASE-CONJUGATE OSCILLATOR IN A COMBUSTING ENVIRONMENT

Abstract
We report on the use of a sodium-seeded flame as an amplifying phase conjugator. The environment is unique in that a number density of 10(16) cm(-3) is maintained despite a lateral dimension of 1 mm. We combine two of these optically pumped flames to form a phase-conjugate resonator. Finally, we observe oscillation that is due to the action of a single flame and two pump beams.

ANAMORPHIC OPTICAL-PROCESSING OF MULTIPLE-EXPOSURE SPECKLE PHOTOGRAPHS
OPTICS LETTERS
1986; 11 (7): 410-412
Abstract
Previous methods for analyzing double-exposed speckle photographs provide point-by-point velocity information by using two-dimensional Fourier analysis, or constant velocity contours by using spatial filtering techniques. A new method using an anamorphic optical system to measure one component of the velocity throughout a section of the flow is analyzed and demonstrated. A laser sheet, thin in the x direction and extended in the y direction, is used to probe a line of the photograph of which the anamorphic optical system forms a one-dimensional Fourier transform in the x direction and images the speckle pattern in the y direction for measuring the x-velocity component. This results in curved fringes, which have a local spacing inversely proportional to the x-velocity component at that point. Thus it is possible to measure a velocity component along a selected line in the flow. This differs from spatial filtering techniques that produce contours showing the points where a selected velocity occurs.

PHASE CONJUGATION IN A FLAME
OPTICS LETTERS
1985; 10 (6): 264-266
Abstract
The first observation to our knowledge of degenerate four-wave mixing in a sodium-seeded flame is reported. In addition, the theoretical dependence of the phase-conjugate output on the sodium concentration is verified experimentally, demonstrating the potential of this procedure for use as a diagnostic tool to measure species concentration in combusting or noncombusting media.

REAL-TIME ENHANCEMENT OF DEFECTS IN A PERIODIC MASK USING PHOTOREFRACTIVE BI12SIO20
OPTICS LETTERS
1985; 10 (9): 430-432
Abstract
The first known experimental results of real-time optical defect enhancement of a periodic mask are reported. A low-intensity reference wave interferes with the Fourier transform of an object beam to form a hologram in a photorefractive crystal. The nonlinear properties of the crystal perform a filtering operation, and phase-conjugate readout results in a defect-enhanced image. Defects of size 10 microm x 100 microm have been easily detected with high signalto- noise ratio, and a discussion of performance limitations is presented.

OPTICAL IMAGING APPLIED TO MICROELECTRONIC CHIP-TO-CHIP INTERCONNECTIONS
APPLIED OPTICS
1985; 24 (17): 2851-2858
Abstract
An imaging system is proposed as an alternative to metallized connections between integrated circuits. Power requirements for metallized interconnects and electrooptic links are compared. A holographic optical element is considered as the imaging device. Several experimental systems have been constructed which have visible LEDs as the transmitters and PIN photodiodes as the receivers. Signals are evaluated at different source-detector separations. Multiple exposure holograms are used as a means of optical fan out allowing one source to simultaneously address several receiver locations. Limitations of this technique are also discussed.
