Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

Solutions to the band-transport equations are developed to include effects on the amplitude,
dynamics, and spatial-frequency response of the space-charge field when periodic or dc …

This paper investigates the possibilities of complex nonlinear dynamic signal generation
using a simple photorefractive two-wave mixing system without any feedback using …

The fundamental component of the space-charge field in a photorefractive crystal is studied
in the presence of an applied alternating electric field. A general equation for the amplitude …

The coupled-wave theory is extended to analyze the two-wave mixing interaction under an
alternating electric field in a sillenite crystal. Within the undepleted pump beam …

In general, the application of an electric field to a photorefractive material with optical activity
results in a change in the effective electro-optic coefficient, r eff, which, in turn, alters the …

We derive an analytic expression describing the intensity and field frequency dependence of
photorefractive gain in two-beam coupling under an alternating square-wave electric field …

The evolution of polarization in holographically coupled beams traversing bismuth silicon
oxide (BSO) in the E?(1¯ 10) configuration is analyzed. The phenomena of electrical …

A vector approach is used to solve four-wave mixing in cubic, optically active, photorefractive
media for the case of undepleted pumps and in the absence of absorption. It is shown that in …

It is shown that a subharmonic grating may have two different phase relationships relative to
the fundamental grating, leading to the appearance of domains. The subharmonic beam is …
