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 theoretical analysis is presented of two-wave mixing in photorefractive materials in which
the complex amplitude of a weak signal beam has slowly varying but otherwise arbitrary …

The effect of a position-dependent time constant on nondegenerate photorefractive two-
wave mixing is analyzed. For codirectional two-wave mixing the results indicate that the …

We investigate the dynamics of multiple two-wave mixing in photorefractive materials. This is
the first time to our knowledge that a study of the dynamics of many pairs of two-wave mixing …

In the twenty years since the discovery of the photorefractive effect [4.1], it has proven to be
both a nuisance and an asset to the optics community. Originally, it was labelled" optical …

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 …

The recent study of nonlinear optical properties of photorefractive materials has led to the
experimental observation of anisotropic energy transfer in two-wave mixing, l the …

We obtain analytical solution to the slowly varying envelope wave equations describing two-
wave mixing in photorefractive crystals with arbitrary dependence of the gain and absorption …

The facility to control light with light is becoming a key function for advanced photonics
architectures. The photorefractive effect is an optical nonlinearity that allows two or more …
