We present a comprehensive analysis of the evolution of a grating envelope, in both
transmission and reflection geometry, during the erasure process in various readout …

Data from measurements of optical absorption, photoconductivity, dark conductivity,
thermally stimulated conductivity (TSC), and thermoluminescence (TL) on samples of …

We report on numerical simulations of two-wave mixing of Gaussian beams in
photorefractive materials. By using a model that takes the lateral intensity distribution of the …

In this paper we review four photorefractive devices which have been investigated and
further developed in our laboratories. We discuss the fundamental behavior of a …

We present an analysis of what is called parametric oscillation in photorefractive media. It is
shown theoretically that when a running grating and a constant electric field are applied to a …

Development of scattered radiation in the geometry of a double phase-conjugate mirror is
investigated numerically in the framework of a two-dimensional model that accounts for both …

The photorefractive effect [1] can loosely be defined as a light-induced change in the optical
properties of a material when the incident light is spatially nonuniform. The spatial …

A finite difference method is used to analyze the behavior of photorefractive InP: Fe at high
fringe contrast under externally applied field. The evolution with increasing fringe contrast m …

The photorefractive effect was first observed in LiNbO 3 more than 25 years ago [[1]]. Since
that time a wide variety of inorganic systems have been shown to be photorefractive …

Bismuth metal oxide sillenites ($ Bi\sb {12} SiO\sb {20} $, $ Bi\sb {12} GeO\sb {20} $, and $
Bi\sb {12} TiO\sb {20} $) are widely used as photorefractive elements in optical systems …
