The photorefractive recording process as described by Kukhtarev's material equations is
investigated for large modulation depths. We find that for modulation 1 the density ND+ of …

Abstract Bismuth tellurium oxide (Bi 2 TeO 5) is a new material expected to exhibit nonlinear
properties because of its noncentrosymmetric crystal structure. A conventional crossed cw …

High-order spatial harmonics of photorefractive gratings are detected directly in multiwave
mixing experiments in photorefractive AlGaAs/GaAs quantum wells operating in the Franz …

The operation of novelty filtering is demonstrated using a hybrid optical and digital system.
Dynamic gratings are written in photorefractive Bi 12 SiO 20 at 514 nm and read out at 633 …

A photorefractive time correlation motion detector is demonstrated. This device overcomes
the material response time limitation associated with other photorefractive motion detectors …

We report the first observation of the photorefractive effect in cadmium sulfide at low optical
power. The maximum gain coefficient measured with no applied field at 633 nm is 0.3 cm− 1 …

We demonstrate a self-organizing system based on photorefrac (cid: 173) tive ring
oscillators. We employ the system in two ways that can both be thought of as feature …

The photorefractive band transport model is extended to include magnetic effects. The
Newtonian equation of motion for electrons in the conduction band under combined electric …

A novel concept for implementing a high-resolution spatial light modulator using a thin slab
of photorefractive LiNbOs crystal is described. This method uses the photovoltaic effect to …
