Abstract :
A monolithic smart pixel technology based on the integration of two-dimensional arrays of cascadable optical switches, optical logic gates, and optical switching nodes consisting of vertical-cavity surface-emitting lasers and heterojunction phototransistors or photothyristors is described. Different combinations of these components perform optical switching, logic, routing, memory, and regeneration. Latching, nonlatching, and bistable switches with high optical gain and contrast are demonstrated, along with all the simple single-stage Boolean optical logic functions. A 2×2 optical bypass-exchange node and a reconfigurable, multistage, two-dimensional optical switching network architecture are also described
