Abstract
Gallium Arsenide (GaAs) is the most technologically-important compound semiconductor for electronics and optoelectronics. Semi-insulating Cr-doped and undoped GaAs crystals are known to be photorefractive.1,2 This provides opportunities to use GaAs for optical processing, including spatial light modulation. In this paper, we will present recent results of our investigation on the feasibility of using GaAs in this area.
