Abstract:

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