Light-induced changes in optical properties such as refractive index and absorption
coefficients are always related to material excitation, ie deviation from (thermal) equilibrium …

The holographic double-exposure technique is applied to elementary gratings in
photorefractive crystals. The result is an interconnection strength that is a continuous …

A model is described for the simulation of photoreflectance spectra from GaAs/GaAlAs
heterojunctions. The Franz‐Keldysh theory is used to obtain the field‐induced modulation of …

This is the first of two volumes that review, for the first time, all major aspects of
photorefractive effects and their applications. Photorefractive effects in electro-optic crystals …

We present a new approach to measure the phase shift between the photorefractive grating
and the interference pattern in two-wave-mixing experiments. This approach is based on …

We report observation of a rotation in the polarization of the two photorefractive recording
beams in GaAs for a configuration with the internally generated space‐charge field along …

It is shown that spatial gratings in photorefractive crystals, induced by the standing
interference pattern of two coherent waves and an external alternating electric field, may be …

The photorefractive response with moving gratings is investigated both numerically and
experimentally under varied fringe-velocity and modulation-depth (m= 0.002 to m= 1) …
