Paper Abstract

Novel multiple quantum well (MQW) optical light modulator structures using the quantum-confined Stark effect induced by a propagating surface acoustic wave, are described. The proposed structures are shown to generate electric field strengths in the range required to produce significant shifts in electroabsorption and index of refraction for the AlGaAs-GaAs system. The operation of a Bragg modulator/switch, which utilizes the QCSE to enhance the diffraction effects and forms an acoustic phase grating produced by the SAW beam, is also discussed. The schematics of an integrated spatial light modulator based on enhanced Bragg modulation is presented. In addition , the application of spatial light modulators and the optical devices in the realization of an optical correlator is discussed.
