Experimental demonstration of all optical XOR logic using SOA based Mach-Zehnder interferometer

We propose and demonstrate all optical XOR logic implemented with SOA based Mach-Zehnder Interferometer, simulated at ultrahigh speed of 40 Gbps. XOR logic is a vital element for signal processing. Non linear characteristics of SOA i.e. cross phase modulation is exploited for XOR logic design. Obtained results confirm the feasibility of XOR logic.
