Abstract

An all-optical pseudo random binary sequence (PRBS) generator is designed using hard- limiters and serially interconnected D flip-flops based on two coupled polarization switches (PSWs). The performance of the circuit is evaluated through numerical simulation to confirm its feasibility in terms of the choice of the critical parameters. The proposed scheme is theoretically demonstrated for a 3-bit and 5-bit degree PRBS and can be extended to higher order.
