Abstract : Our research effort at UCSD has been to develop hybrid optical electronic processing systems capable of high speed computing. We have identified several approaches to hybrid processing worthy of intensive study: (1) optical analog/electronic digital hybrids, employing either a coherent optical processor or a confocal opitica feedback system, and (2) optical digital (nonlinear)/electronic digital hybrids, employing either optical parallel logic or integrated optical logic devices. These approaches are worthy of intensive study because optical computation offers the unmatched capabilities of parallelism while electronic computation is currently more flexible. Our focus, then, is to combine the powerful features of both optical and electronic computation. (Author)
