Abstract

This paper discusses optoelectronic processes in an optical system with two-dimensional feedback, based on a metal-insulator-semiconductor-liquid-crystal structure. The dependence of the diffraction-spreading factor on voltage is obtained, along with its dependence on the parameters of the semiconductor and the liquid crystal. Estimates are given of the autovibration period and of the possible contribution of drift of the carriers over the aperture in spatiotemporal light modulators under the action of the field components in the transverse directions.
