Real-Time Implementation of Nonlinear Optical Processing Functions.
Abstract
For the past two decades optical data processing (ODP) has promised a vast increase in processing capacity and speed over conventional electronic techniques. This promise has never been fulfilled for several reasons, most notably because of the lack of a practical real-time image modulator, or light valve, and because optical techniques were almost exclusively limited to linear operations. These restrictions have been removed by the development of the liquid-crystal light valve (LCLV) by Hughes Research Laboratories (HRL), and by nonlinear parallel-processing techniques developed by the University of Southern California (USC). Thus, it is important to determined how successfully nonlinear parallel-processing techniques can be implemented in real time with the various LCLVs. In addition, other new optical technologies, highly developed at HRL, such as four-wave mixing and phase conjugation have inspired a novel research direction for this program in the field of optical associative memories and neural networks as models for computing. Here the phase conjugation provides the desired nonlinearities.
