Abstract : An optical flip-flop system having a pair of optically aligned nonlinear Fabry-Perot etalons, one of which acting as a bistable optical device, the other acting as a negative optical gate. The negative optical gate is initially tuned for high transmission and will remain transmissive until impinged upon by a first optical pulse, at which time it will momentarily become nontransmissive. It this nontransmissive state is longer than the recovery time of the bistable optical device, then the bistable optical device will remain nontransmissive until impinged upon by a second optical pulse. There-upon, the bistable optical device will transmissive until such time the negative optical gate becomes nontransmissive again. In this manner the flip-flop system can be readily controlled by the application of the pair of optical pulses thereto. (Author)
