Photorefractive Crystals
Photorefraction is an effect of refractive index variation
in the material exposed to the light. This property makes it possible to create spatial
distribution of refractive index in the crystal and can be used in wide variety of devices
including spatial light modulators, optical memory, holography, phase conjugation etc.
Most popular photorefractive crystals are Fe:LiNbO3 and crystals of Sillenite
structure Bi12MO20 (M = Si, Ge, Ti). These crystals have fortunate
combination of photorefractive, electrooptic and other properties making it promising
materials for optoelectronics.
