Abstract

An all-optical nonlinear threshold gate based on weakly-coupled, high-order microring resonators were investigated using the transmission matrix formalism. A Kerr nonlinear enhancement factor of exceeding 2.5x10³ can be obtained at the ring-coupling coefficient of 0.02. Simulation results show that the nonlinear optical threshold gate has a sharp optical intensity-dependant switching property with a low switching threshold (> 80%) of -10dBm.
