Paper Abstract

The minimum power (=5 mW) for room-temperature optical bistability is very similar in bulk and multiple-quantum-well (MQW) etalons. No exciton resonance is obvious in the absorption spectrum of bulk GaAs at 300 K because it blends into the band edge, but it is present, and its area is two-thirds that of the MOW heavy-hole exciton. It is shown that the excitonic nonlinear index change is consistent with the observed bistability.
