Abstract
The nonlinear optical response of an asymmetric lambda/4-shifted distr ibuted-feedback GaAs/AlAs heterostructure is investigated using numeri cal methods, and also demonstrated experimentally. This structure exhi bited both optical switching and bistability at incident wavelengths n ear lambda=884 nm. The observed bistability threshold of less than 1 k W cm(-2) is more than an order of magnitude smaller than that of any p reviously measured distributed-feedback heterostructures.
