An optical decision circuit is constructed by modifying the stability conditions of a previously introduced optical flip-flop memory (Appl. Phys. Lett., vol. 88, p. 181 118, May 2005). The simulations using a rate-equation model of the circuit predict fast operation speed (rise and fall times of the...
