Abstract :
An all-optical AND logic gate based on the four-wave mixing (FWM) effect in an InGaAsP-InP microring resonator side-coupled to a bus waveguide, is proposed and simulated. Using an ultrafast nonlinear process such as FWM, operation at a bit rate up to 160 Gb/s is demonstrated for the return-to-zero modulation format.
