Abstract
We report the observation of bistability in the photocurrent and photoluminescence spectra of GaAs quantum well heterostructures. The excitation energy is nonresonant and above the band-gap energy of the barrier. A self-consistent calculation taking into account the rate equations governing the charge distribution in the wells is shown to result in the observed bistability which leads to a new class of optically bistable devices.
