Abstract :
A recognized model for an all-optical digital computer consists of arrays of optical logic devices interconnected in free space. In order to simplify device requirements and to reduce the complexity of the optics, regular interconnects between logic gates are considered such as crossovers. Problems and solutions related to the computer-aided design of these systems are identified, such as layout, fault avoidance, pipelining, and other considerations. An algorithm for determining settings for an optical programmable logic array that maintains a strict crossover interconnect at the gate level is described as an example of computer-aided design applied to this model.<>
