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 …

A theoretical and experimental study of photorefractive nonlinear multi two-wave mixing is
given. It is used to describe the fanning effect, which is an asymmetric self induced light …

A novel method for the exact solution of four-wave mixing in photorefractive media is
presented. This method allows us to treat exactly the effects of nonequal angles of …

Volume 61). Hard cover DM 119,-. ISBN 3-540-18332-9 This is the first of two volumes that …

We report on a photorefractive polymer with a 4-ms-response time in transient four-wave
mixing experiments at 0.5 W/cm2 writing irradiance, 95 V/m applied electric field, and a …

A brief review of a band transport model for the photorefractive effect is given. Distinction is
made between the influence of intrinsic material dependent parameters and externally …

In this chapter, the standard model accounting for the photorefractive nonlinearity in a
material is presented. The mathematical formalism of the rate equations has been …

Photorefractive materials offer the possibility of optical signal processing at milliwatt power
levels. The potential applications of photorefraction for optical if formation recording …

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 …

We show that photorefractive materials having large electro-optic coefficients such as
BaTiO3 require relatively small electric field to induce sufficient phase mismatch for the …
