Evaluation of the Current Biased Integrated Optical Processors Based on BistableDode Elements

摘要

Three optical switching elements have been designed, fabricated and tested foruse in an integrated, optical signal processor. The first, and optical NOR logic gate, uses gain quenching as a means of allowing one (or more) light beam (s) to control the output light. This technique, along with the use of a two-pad bistable output laser, is used in the demonstration of the feasibility of the second device, an all optical RS flip-flop. The third device consists of a broad area orthogonal mode switch laser, whose corollary outputs correspond to the sign of the voltage difference between its low to high impedance electrical inputs. This device also has possible memory applications if bistable mode switching within the broad area laser can be achieved.
