The band transport model describes charge statics and dynamics within photorefractive
materials. Here a steady-state solution is found for the setting in which an arbitrary optical …

The band transport model is used to derive the space-charge field induced by an optical
beam propagating in photorefractive materials with the application of an external dc field in …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

The photorefractive band transport model is extended to include magnetic effects. The
Newtonian equation of motion for electrons in the conduction band under combined electric …

The partial differential equations of Kukhtarev et al.(1977) which describe the time
dependence of hologram formation in photorefractive materials are solved analytically in the …

The steady‐state space‐charge field and the response time of a photorefractive material
illuminated with a sinusoidal interference pattern are derived for two models in which both …

A two-dimensional time-dependent analysis is presented to describe photorefractive
recording in a film with anisotropic transport parameters. The solution of the rate equations …

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 …

The response of photorefractive materials to sinusoidal intensity patterns of high modulation
depths is considered. It is shown that the induced refractive-index response in this regime is …

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 …
