Abstract

The current interest in GaAs/AlGaAs multiple quantum well (MOW) materials has developed because of unique electronic and optical properties due to the presence of the 2-D room temperature excitons in these structures.¹ Applications of multiple quantum wells to modulators and detectors have previously been reported.² Only recently, however, have the excitonic properties of quantum wells been exploited in optical waveguide geometries.^3,4 Here we present results of a study on single-mode multiple quantum well asymmetric slab waveguides using the grating coupling technique.
