All-optical flip-flop operations in a coupled element bistable device
Kenju Otsuka · Electronics Letters · 1988
An optical bistable device composed of coupled nonlinear elements is proposed. This device features optical bistability without hysteresis. It is shown theoretically that a set-reset type (S-R) flip-flop operation can be easily achieved on an all-optical basis by utilising nonhysteretic bistable characteristics.
