Paper Abstract

The fundamentals of noncollinear coplanar guided-wave acoustooptics and some of the more recent progress on application of the resulting devices are summarized in this paper. First, basic interaction mechanisms, configurations, and key acoustical and optical parameters are discussed. A number of wideband device configurations which employ isotropic/anisotropic Bragg diffractions and multiple surface acoustic waves together with the results obtained using optical waveguides in Y-cut LiNb03 substrate are then described. Finally, typical performance figures that have been obtained with applications using the resulting wideband devices, emphasizing those being carried out at the author's institution, including high-resolution light beam deflectors, very high-scanning rate light beam deflectors, spectrum analyzers, convolvers, pulse compressors, and tunable optical filters are given. Further improvements in performance figures as well as implementation of other types of signal processors are possible. These applications constitute some of the attractive ones in future wideband multichannel integrated/fiber optic communication and signal processing systems.
