Theoretical and experimental investigations of the linear and nonlinear space–charge field
effects in photorefractive materials are reviewed. In particular, the aim is to explore the …

We present the first complete theoretical model that describes the formation of the space-
charge field in a photorefractive material that is exposed to a sinusoidal ac electric field with …

We consider the process of nonstationary enhancement of the photorefractive effect through
the application of time-varying (square-wave) electric fields. By examining the full second …

A phenomenological approach, in which the current density is related in some functional
manner to the electric field and to the light intensity, is developed. The validity and …

Light-induced charge transport processes are essential for photorefractive effects in
electrooptic crystals. Charge driving forces, charge transport models and experimental …

A theory of rectifying electric fields associated with photorefractive waves is presented. The
rectification effect is caused by scattering of photorefractive waves from the static grating of a …

From thermodynamic considerations, we derive a consistent set of equations coupling the
steady-state photoinduced photorefractive space-charge field to mechanical deformations …

A new model of two species of electron–hole with shallow electron trap is presented. The
model predicts that if the shallow trap accumulates large density of charge carriers, the …

The response of photorefractive materials is considered when there is no optical input but
previous optical excitation is taken into account by a set of initial conditions. The temporal …
