Abstract

The coupling kinetics of a reflection-type photorefractive hologram are studied, and we have found that the coupling between the adjacent channels increases as the reading time is prolonged. Our study-shows that the reading beam is modulated by the grating in another channel for which it produces a weak backscattered light. As the backward-scattered light interacts with the reading beam, a new grating is formed; it in turn amplifies the backscattered light. Therefore the coupling increases rapidly compared with the normal fanning process. We have used Kukhtarev’s charge-transport model to evaluate the time evolution of coupling. The calculated results are consistent with the experimental observation.
