Photorefractives for Optical Signal Processing

Abstract

Photorefractive recording dynamics of two-beam coupling were investigated theoretically and experimentally. The interaction of beams with slightly different frequencies were studied in semi-insulating semiconductors. The influences of bulk absorption, Gaussian beam profiles and experimental geometry on the temporal response were analyzed. These effects were shown to narrow the response bandwidth. Enhancement of the steady-state photorefractive response in tin hypothiodiphosphate (Sn2P2P6) by use of the moving grating technique, without an applied electric field, was demonstrated.
