The role of fiber optics as an interconnection mechanism for optoelectronic programmable logic arrays (OPLA's) is critically examined. The effect of fundamental physical limitations on the computational capacity of OPLA's is considered. A comparison of OPLA technology to that of existing electronic logic arrays is presented, and scaling relations are derived. The role of higher order decoders in minimizing the requirements on computational capacity is delineated. A novel technique is proposed for effecting a reconfigurable equivalent to a spatial light modulator based logic system.
