Paper Abstract

Two-dimensional spatial light modulator (SLM) structures, employing a novel multiple quantum well (MQW) light valve, are proposed for optical signal processing applications. The optical modulation in the light valve is achieved by the manipulation of field-dependent birefringence in the MQW layers. This is in contrast with the conventional MQW modulators which generally involve amplitude modulation by varying the electroabsorption. Computations of enhanced birefringence (in) due to quantum confined Stark effect (QCSE) as a function of wavelength are presented for the AlGaAs-GaAs MQW layers. MQW light valve configurations using both reflection and transmission mode of operations are discussed. A two-dimensional SLM utilizing InGaAs-GaAs MQW layers, an AlAs-GaAs λ/4 wave stack as dielectric mirror, and an array of integrated InGaAs-GaAs photodetector elements is described.
