Abstract

Although a variety of optical computing architectures have been analyzed and many individual devices reported, to date few working optical computers have been demonstrated performing a complete, self-contained, recognizable computational function. A conceptually simple but significant computing architecture which appears accessible to complete all-optical implementation is the cellular automaton (CA). Murdocca discussed the CA in comparison with symbolic substitution (1). Taboury et al showed how general cellular processors could be realized using sets of holograms (2).
