Regular free-space interconnects such as the perfect shuffle and banyan provided by beam
splitters, lenses, and mirrors connect optical logic gates arranged in 2-D arrays. An …

From the Publisher: Optical computing can have significant advantages over electronic
computing in terms of system speed, but only if the digital design exploits regularity. The …

A general technique is described for implementing sequential logic circuits optically. In
contrast with semiconductor integrated circuitry, optical logic systems allow very flexible …

An optical design of a time multiplexed nonblocking space switch is described for optically
nonlinear arrays of logic devices interconnected in free space. Regular interconnects in the …

This book deals with devices that spatially modulate a beam of light. In digital form, these
devices are basically an array of optical switches that either transmit or block light. Large …

Experimental results are presented showing all-optical programmability and operation of a
multifunction Boolean logic gate. All eight symmetric two-input logic functions have been …

This paper concerns binary digital computing systems in which the information-carrying
medium consists entirely or primarily of photons. The paper begins with a review of analog …

The results of investigations into the feasibility of incorporating optically bistable elements
into an optical processor are presented. Two forms of bistable device, etalons of InSb and …

Within the past 15 years there has been significant progress in the development of two-
dimensional arrays of optical and optoelectronic devices. This progress has, in turn, led to …

This paper describes a new optical gate for logical processing in parallel. The gate consists
of two spatial light modulators which spatially modulate a lightwave by the longitudinal …
