Paper Abstract

Recent advancements in guided-wave acoustooptic Bragg modulators/deflectors1-4 and geodesic lenses have paved the way for real-time processing of wideband multichannel signals in a planar substrate. The encouraging progress obtained in semiconductor diode lasers and photodetector arrays, and in the mechanisms for butt-coupling these components to planar waveguides also points to a good prospect for hybrid integration of all components in LiNb03 and Si substrates. Fig. 1 depicts the configuration of an acoustooptic time-integrating correlator using hybrid integration in LiNb03 substrate.5 Naturally, present and future research in GaAs sub-strate may also result in monolithic integration. The resulting integrated optic modules or subsystems are expected to provide improvements in size and weight, performance, reliability, and ultimate cost.
