Major Initiatives For Optical Computing

Optics is under serious consideration with regard to the implementation of parallel multiprocessing systems, especially those involving a high degree of interprocessor interconnection. This paper discusses multiprocessing architectures and describes the developing technology directed toward advanced multiprocessor machines that is supported by the Defense Advanced Research Projects Agency (DARPA). The emerging device and materials technology is discussed. The major device development is categorized into four areas: sources and detectors integrated with electronics, two-dimensional spatial light modulators, optical beam steering, and bistable optical devices.
