Abstract

A nonlinear plasmonic T-shaped switch based on a square-shaped ring resonator is simulated by the finite-difference time-domain numerical method. Three optical logic gates—a NOT, with one T-shaped switch, and AND and NOR gates, each with two cascaded T-shaped switches—are proposed. The nonlinear Kerr effect is utilized to show the performance of our proposed logic gates. The values of transmission at the ON and OFF states of NOT and NOR gates are 70% and less than 0.6% of the input lightwave, respectively, while these values for the AND gate are 90% and less than 30%, respectively.
