Abstract

ZnTe/CdZnTe multiple quantum wells (MQWs) optical bistable device has been fabricated, and optical bistability in ZnTe/CdZnTe MQWs optical bistable device is investigated on transmission at room temperature. The research result indicates that the threshold and contrast ratio for the optical bistability in Zn-Te/CdZnTe MQWs optical bistable device are about 363 kW/cm² and 4:1, respectively. On the basis of the excitonic nonlinear theories, excitonic absorption spectrum in the ZnTe/CdZnTe MQWs obtained here, we attribute the major nonlinear mechanism for the optical bistability to the saturating effect of excitonic absorption.
