Abstract:
There is a growing demand for nonlinear optical materials for a variety of applications—lasers and coherent sources, electrooptic devices, communication technologies, and optical processors and computers. Nonlinear optics is a vast field requiring materials with diverse performance features. Photorefractive (PR) materials, which experience a change in the refractive index under the effect of inhomogeneous illumination, constitute a relevant branch of the field. They behave as third-order nonlinear materials, which can be considered, in general, as photorefractive. However, the materials more commonly designated as photorefractives involve a charge-transport-induced nonlinearity, and it is these materials which are the object of this issue of the MRS Bulletin.At variance with conventional (often designated as Kerr) nonlinear materials, photorefractives are sensitive not to the local light intensity but to its spatial variation; i.e., they are nonlocal materials. This feature makes them more complicated to deal with than their conventional counterparts, since a χ(3) susceptibility cannot be properly defined (except as a k-dependent function). On the other hand, this sensitivity gives them some unique and interesting features. In particular, an interference light pattern illuminating the crystal and the generated index grating are phase-shifted, leading to remarkable beam coupling and amplification effects. The coupling gain can be markedly enhanced by applying alternating electric fields or by oscillating the interference fringes with a piezoelectric mirror. Efficient image amplifiers have been made using this effect.

Abstract:
Sc:Ru:Fe:LiNbO3 crystals were grown from congruent melt by using the Czochralski method. A series of LiNbO3 crystals (Li/Nb = 48.6/51.4) with 0.1 wt% RuO2, 0.06 wt% Fe2O3 and various concentrations of Sc203 were prepared. RF1 and RF4 refers to the samples containing 0 mol% Sc203 and 3 mol% Sc203, respectively. The photorefractive properties of RF4 were measured by Kr+ laser (λ = 476 nm blue light): ηs = 75.7%, τw = 11 s, M/# = 19.52, S = 2.85 cmJ−1, Γ = 31.8 cm−1 and ∆nmax = 6.66 × 10−5. The photorefractive properties of five systems (ηs, M/#, S, Γ and ∆nmax) under 476 nm wavelength from RF1 to RF4 continually increased the response time, while τw was continually shortened. Comparing the photorefractive properties of Sc (1 mol%):Ru (0.1 wt%):Fe (0.06 wt%): LiNbO3 measured by Kr+ laser (λ = 476 nm blue light) with Sc (1 mol%):Fe (0.06 wt%):LiNbO3 measured by He-Ne laser (633 nm red light), ηs increased by a factor of 1.9, Vw (response rate) increased by a factor of 13.9, M/# increased by a factor of 1.8 and S increased by a factor of 32. The ∆nmax improved by a factor of 1.4. A strong blue photorefraction was created by the two-center effect and the remarkable characteristic of being in phase between the two gratings recorded in shallow and deep trap centers. The photorefractive properties (ηS, τw, M/#, S, ∆nmax) were increased with an increase in Sc3+ ion concentration. Damage-resistant dopants such as Sc3+ ions were no longer resistant to damage, but they enhanced the photorefractive properties at the 476 nm wavelength. The experimental results clearly show that Sc-doped two-center Ru:Fe:LiNbO3 crystal is a promising candidate blue photorefraction material for volume holographic storage. Sc-doped LiNbO3 crystal can significantly enhance the blue photorefractive properties according to the experimental parameters. Therefore, the Sc:Ru:Fe:LiNbO3 crystal has better photorefractive properties than the Ru:Fe:LiNbO3 crystal.

Abstract:
Photorefractive two-beam coupling is examined experimentally for the case of high modulation depth. It is seen that the dynamics of signal growth and decay are best described by a double exponential function. The properties of this function with respect to interaction angle and modulation depth are studied. It is suggested that the equations governing photorefractive dynamics may be reduced to a pair of coupled bilinear rate equations which adequately describe photorefractive dynamics for high modulation depth.

Abstract:
MgO-doped LiNbO3 (LN:Mg) is famous for its high resistance to optical damage, but this phenomenon only occurs in visible and infrared regions, and its photorefraction is not decreased but enhanced in ultraviolet region. Here we investigated a series of ZrO2 co-doped LN:Mg (LN:Mg,Zr) regarding their ultraviolet photorefractive properties. The optical damage resistance experiment indicated that the resistance against ultraviolet damage of LN:Mg was significantly enhanced with increased ZrO2 doping concentration. Moreover, first-principles calculations manifested that the enhancement of ultraviolet damage resistance for LN:Mg,Zr was mainly determined by both the increased band gap and the reduced ultraviolet photorefractive center O2−/−. So, LN:Mg,Zr crystals would become an excellent candidate for ultraviolet nonlinear optical material.

Abstract:
We have determined that the dynamics of the signal in photorefractive two beam coupling can be described by a memory effect in the writing of the space charge field. Experimental and computational results confirm that this time dependence is dependent on the history of interference pattern responsible for the space charge field. From this memory effect it is shown that if the input signal has a sinusoidal component much smaller than its DC component, the sinusoidal component of the two beam coupled signal is shifted by the response time of the photorefractive medium. We have demonstrated, both theoretically and experimentally, that for the non-depleting pump this response time is linear with the interaction length.

Abstract:
Photorefractivity has attracted intense attention owing to its ability to spatially modulate the refractive index under non-uniform light illumination. In particular, photorefractive polymers are appealing materials as they enable the high non-linear performance that underpins many areas of photonics. The incorporation of nanoparticles into photorefractive polymers shows an enormous potential owing to the broad spectroscopic tuning range and the high photogeneration efficiency, which are inaccessible to traditional photorefractive materials. This article reviews the recent developments in the field of nanoparticle-doped photorefractive polymers. The merit and functionality of these hybrid materials are summarized and future challenges are discussed. The application of nanoparticle-doped photorefractive polymers under two-photon excitation is also described, which facilitates a promising new area of high-density optical data storage, the third-generation of optical data storage.

Abstract:
The work presented in this thesis is derived from experimentation in the field of polymeric photorefractive materials. Low T(_g) polymeric composites were prepared, based on the well-known photoconductive polymer PVK (maximum 50% w/w), sensitized with TNF (2% w/w) and C(_60) (0.2% w/w), plasticized with ECZ (maximum 49.3% w/w) and doped with the nonlinear optical materials NPP (50% w/w), DAN (20% w/w), DED (5% w/w), DCNQI (0.5% w/w), ULTRA-DEMI (5% w/w) and DI-DEMI (2% w/w), and their dielectric, linear and non linear optical properties were investigated. All the materials, except DCNQI, exhibited good solubility and sample processibility. The dielectric properties of the composites at 1 KHz and 1 MHz were determined using a parallel-plate capacitance bridge. The dielectric constant and loss at 10 GHz were measured using a novel adaptation of the resonant cavity technique, which was designed for measurements at ambient and elevated temperatures. The method was used to measure of the dielectric constant and loss of two novel, high T(_g), electro-optic polymers at temperatures up to 100 ºC. The dielectric properties measured were typical of polymeric materials. The absorption coefficient and the refractive index at different wavelengths were measured using a spectrophotometer. For the refractive index, an interference fringe analysis was used. The nonlinear measurements consisted of second harmonic generation, to prove the nonhnearity of the composites, two-beam coupling measurements, to prove their photorefractivity and degenerate four-wave mixing to measure their diffraction efficiency. The NPP, DAN, DED and ULTRA-DEMI doped investigated composites exhibited second order nonlinearity with highest the one of ULTRA-DEMI, at 292 pm/V for 19 kV of corona poling field. The photorefractivity of the NPP, DAN and DED doped composites was proven at 632.8 nm, while ULTRA-DEMI doped composites photooxidized before any measurements were possible. The two-beam coupling coefficients measured were lower than 20 cm(^-3), while net gain was observed only in the NPP doped composite. The diffraction efficiencies of the NPP, DAN and DED doped composites were measured at 632.8 nm, and were found to be l0(^-5)-l0(^-6).

Abstract:
Real time holography in photorefractive materials has been considered for many applications, most recently to provide the reconfigurable interconnections in optical neural net computing.1 In these applications the existing holographic grating pattern must be erased and a new pattern written within the cycle time of the computer. The usual procedure for erasure is to flood the crystal with a separate erase beam or to use one of the write beams alone as the erase beam. We present a simple technique for rapid erasure by shifting the phase of one of the write beams by λ/2. This technique gives an almost complete erasure and is at least 8 times faster than using one of the write beams alone to erase.

Abstract:
Photorefractive materials, for instance photorefractive crystals and photorefractive ceramics to which our main interest is dedicated, are of importance for optical storage applications. The dynamic-holographic recording process as well as the process of reading out a stored hologram, however, may be strongly disturbed by a simultaneous increase of scattered radiation. This “holographic scattering” has first been observed as early as 1971 by Amodei and Stäbler [1] in LiNbO3. In LiNbO3 it has further been investigated in references [2] to [9], in LiTaO3 in references [6, 10], in (Sr x :Ba1− x )1− y /(Nb2O6) y in references [11, 12], and in BaTiO3 in references [6, 7, 13, 14, 15, 16, 17]. The effect is believed to result from random gratings written by the beams illuminating the material and by light scattered from inhomogeneities of the material [3]. As a transient effect, amplification of the scattered radiation is typical. For the stationary state, however, amplification or decrease of the scattered radiation is possible [18]. The whole process is an exciting but complicated example of dynamical holography [19].

Abstract:
The electrooptic properties of photorefractive materials are currently under intensive investigation because of their potential applications in real-time holography, optical data storage and phase-conjugate wavefront generation. Recently, increasing attention has been focused on two-beam coupling in photorefractive crystals to achieve coherent signal beam amplification. Applications for this technique include image amplification, vibrational analysis, nonreciprocal transmission, laser-gyro biasing and optical computing. Critical issues for practical application of the photorefractive effect include the material's response time and coupling coefficient. If photoferroelectric crystals are to be used for device applications, their response time must be reduced to the order of 1 msec. or better, and a large photorefractive coupling coefficient is required for the construction of efficient devices. The ideal photorefractive crystal has yet to be discovered; hence a large number of ferroelectric crystal compositions have been grown and characterized. As part of this effort, two-beam coupling has been studied in single crystals (0.5 cm. diameter) of cerium-doped Ba0.5 Sr1.5 K0.5 Na0.75 Nb5 O15 (BSKNN-3) grown at Rockwell International Science Center.

Full text
Abstract:
We experimentally determined materials parameters in photorefractive barium titanate using a Raman-Nath probe technique of laser induced dynamic gratings. In this technique, shown in Fig.1, coherent co-planar writing beams (wavelength λw) propagating in the X-Y plane intersect inside the crystal and form an interference pattern, inducing refractive index grating planes via the photorefractive effect. A probe beam (wavelength λp) propagating in the Z-direction passes through and parallel to the grating planes and is diffracted. The resulting diffraction pattern on a screen which is parallel to the X-Y plane and located beyond the crystal consists of a set of discrete intensity maxima (modes) which are symmetrically located about the m=0 (undiffracted) order. The angle of diffraction, θDm, of a particular mode, m, (where m=0, 1, 2, 3,…, integer) is a function of the ratio of the probe beam wavelength to the grating spacing in the crystal. The grating spacing, ΛG, in the crystal is a function of the ratio of writing beam wavelength to intersection angle of the write beams in the crystal.

Abstract:
In this contribution we analyze the configuration for anisotropic self-diffraction in KNbO3. First applications of this effect in spatial light modulators and incoherent- to-coherent converters are described. Anisotropic Bragg diffraction can occur if off-diagonal elements of the electro optic tensor are involved in the grating formation. In KNbO3 this is the case for r42=380pm/V and r51 =105pm/V (for λ=633nm) [1,2].

Abstract:
Holographic recording of information in electrooptic crystals is based on a light- induced modulation of the elements of the dielectric tensor. For readout of these volume phase holograms the Bragg condition must be satisfied[1]. In birefringent crystals this may be achieved not only for waves with equal polarization (isotropic diffraction) but also for orthogonally polarized waves (anisotropic diffraction) [2].

Abstract:
It has been demonstrated1-4 that GaAs is a sensitive photorefractive material with the potential to be used for optical processing in the infrared region. The advantages of using GaAs crystals for optical processing include: high sensitivity1, low power consumption5, fast response2,6, infrared operation, tunable information storage time, and compatibility with semiconductor lasers4, sensors, and VLSI circuits. The compatibility provides an excellent potential to integrate optical processing devices with advanced technologies of VLSI, lasers, and sensors for the development of future sophisticated information and image processing systems. One of the potential applications of such integrated systems is the optical interconnects for VLSI circuits8.
