Paper Abstract

Optical cellular logic and extended-interconnect cellular logic processor architectures are described. Simulations, tolerance studies and circuit construction are used to advance both device technology and architectural thinking. Benchmarking against electronic distributed array processors leads to an optical non-locally interconnected, off-chip scheme with local electronic connections between smart pixels, unless ultra-low switching energy all-optical components can be fabricated. Fundamental limits to optical bistability do not rule out the latter possibility.
