Abstract :
The authors describe a novel family of versatile, cascadable, optical switches with different functional characteristics-latching, non-latching, and bistable-using a single epitaxial structure based on the monolithic integration of photothyristors and surface-emitting lasers. High-performance optical switching characteristics have been achieved for all three switch archetypes. The authors also demonstrate the AND, OR, NAND, NOR and INVERT optical logic functions using monolithic switch structures.<>
