Abstract :
The normal method of operation for a GaAs MQW quantum confined Stark effect (QCSE) reflection modulator is given for a device operating wavelength, taken as 852 nm for the analysis in this paper. Modulation in the intensity of a reference optical beam is achieved by shifting the wavelength to achieve both low reflectivity and high reflectivity. The figure of merit for a QCSE modulator is its change in reflectivity from the low state to the high state is given.
