An All Optical XOR Logic Gate for NRZ Based on TOAD

摘要：

All-optical XOR logic gate is a basic and crucial element for optical signal processing. With introducing assistant light, we proposed and simulated a novel all optical XOR gate for NRZ based on teraherz optical asymmetric demultiplexer (TOAD). Simulation results shows that this program can get 13.29 dB extinction ratio (ER) of XOR logic operation output. The analysis of impact of nonlinear phase shift difference departure from π and 2π in actual system shows that when a fluctuant rang of nonlinear phase shift difference is confined within 0.1 rad, 13 dB extinction ratio of output is still obtained with assistant light injection. Its validity is confirmed through experiments and simulation at 2.5 Gb/s and 40 Gb/s, respectively.
