ABSTRACT:
An optical flip-flop comprises a phase-conjugating mirror; a one-way mirror having its reflective side facing the phase-conjugating mirror; a "set" light pulse directed towards the phase-conjugating mirror through the transmissive side of the one-way mirror for initiating a reference light beam which thereafter reflects continuously along an auto-collimating path between the mirrors; a normally transmissive optical gate along the path of the reference beam which is rendered nontransmissive relative thereto upon interaction with a "reset" light pulse; a plurality of filters positioned between the mirrors to prevent the self-starting of the reference beam therebetween; and means for deriving an output signal from the reference beam. An optical logic device comprises a plurality of such flip-flops sharing a single set of mirrors, whereby increased system compactness and simplicity is achieved.
