Abstract

A digital optical computing architecture is described that consists of arrays of identical optical logic gates interconnected in free space with regular interconnection patterns. Advantages of this model include massive parallelism, simplicity in device fabrication, tolerance to processing defects, wide bandwidth access to memory, and gate-level reconfigurability. The success of this model relies heavily on advances in device technology, optical systems design, and the ability to map arbitrary digital problems onto the regular structure. Digital design methods are described that address the mapping problem and support a means of recovery from processing defects while supporting new computing paradigms made possible by the underlying technology. The conclusion is made that this approach simplifies requirements of the optical hardware while providing significant computational advantages.
