Abstract
Optical bistability of electronic origin has been observed in strip-loaded waveguides in a GaAs/AlGaAs multiple quantum well structure. Single-mode waveguides were fabricated by reactive ion etching of an epitaxial AlGaAs layer above the quantum wells. The waveguides were operated as nonlinear Fabry-Perot étalons with 30% reflectors provided by the cleaved ends. Phase shifts of 2π were observed in some devices.
