The paper presents an all-optical 3 bit up counter with complete Boolean functionality as a representative circuit for modeling and optimization of monolithically integrated components. Here, the proposed logic unit design is based on nonlinear effects in semiconductor optical amplifiers (SOA).These equations are first solved to generate the pump, probe and conjugate pulses in a SOA. The pulse behavior are analyzed and applied to realize behavior of all-optical NAND gate. Next, the logic is used to implement All-Optical D Flip-Flop logic, and its function is verified with the help of truth table. Finally with the help of three D Flip-Flops, a 3-bit up counter is proposed.
