Thin-Film Acoustooptic and Electrooptic Devices with Applications to Integrated/Fiber Optic Signal Processing and Communications

摘要

During the third program year emphasis of research was placed six subareas, namely, very high scanning-rate light beam deflection/switching, spectrum analysis of very wideband RF signals, wideband AO Bragg cell using multiple tilted transducer but without electronic phase shifters, wideband AO Bragg cell using a tilted-finger chirp transducer, improvement in fabrication capability, and acoustooptic Bragg deflection in crossed channel optical waveguides. Major progress and achievements for each are described: Very High Scanning-Rate AO Light Beam Deflection and Switching; Spectrum Analysis of Very Wideband RF Signals; Wideband AO Bragg Cell Using Multiple Tilted Transducer But Without Electronic Phase Shifters; Wideband AO Bragg Cell Using a Tilted-Finger Chirp Transducer; Improvement in Fabrication Capability; and Acoustooptic Bragg Deflection in Crossed Channel Optical Waveguides.
