Abstract
The effect of wavelength-resonant spacing of the nonlinear material on the switching threshold of an optical bistable switch is studied. The system investigated employs GaAs/AlGaAs multiple quantum wells sandwiched between epitaxial quarter-wave AlAs/AlGaAs multil ay er reflectors. This system provides high reflectivity and a strong resonant nonlinearity whose effect remains spatially well confined. The system is numerically modeled, showing a factor of 3.6 enhancement due to resonant periodic spacing. The model is used to design a structure that was produced by molecular beam epitaxy.
