Photorefractive Materials presents an overview of the basic features and properties of
photorefractive materials, covering a wide array of related topics. It provides a coherent …

Solutions to the band-transport equations are developed to include effects on the amplitude,
dynamics, and spatial-frequency response of the space-charge field when periodic or dc …

The steady-state and dynamic behavior of absorption and phase gratings in semi-insulating
GaAs and InP have been studied by four-wave mixing. These measurements permit …

Two coherent light beams can couple in any absorbing material owing to a light-induced
modulation of the material's dielectric constant. In photorefractive crystals the coupling …

Because of the light-induced bleaching of GaAs at λ= 1.064 µm, the amplitude gratings
strongly affect the photorefractive recording in this material. We extract two contributions that …

We describe how optical beams from a mode-locked laser will couple in a photorefractive
crystal. We show that the two-beam-coupling gain coefficient is proportional to the square of …

Two optical beams can couple in a photorefractive crystal without using the electro-optic
effect. Beam coupling is due to a spatially modulated absorption caused by the …

A small photochromic grating is selectively and continuously detected from a much larger
photorefractive modulation in Fe-doped LiNbO3 crystals in a two-wave mixing experiment …

InP is a key semiconductor for the production of optoelectronic and photonic devices. Its
related compounds, such as InGaAsP alloy, have been realized as very important materials …

Dependence of the phase conjugate signal in photorefractive four-wave mixing on the
crystal orientation and the polarization of the interacting beams is experimentally studied for …
