Two-wave mixing with partially coherent waves in high-speed photorefractive media

摘要

We investigate the coupling of two partially coherent waves in high-speed photorefractive media. When the coherence time of the optical waves is close to the speed of the photorefractive media, the photoinduced index grating will follow the amplitude fluctuation of the optical waves. The stochastic coupled-wave equations are solved in the nondepleted pump region. The effects on the evolution of the signal wave are presented and discussed. (C) 1997 Optical Society of America.
