Abstract

Numerical simulations based on the Finite-Difference Time-Domain (FDTD) method are carried out on the optical add/drop filters consisting of two coupled microring resonators. To realize the broadband switching, suitable value of refractive index discrepancy between the microrings is required. We found that it is the resonant order of ring mode that determines the needed smallest discrepancy to trigger the switch. It points the way for the highly integrated optical devices that require low power consumption. The FDTD results can be explained by the concept of coherent superposition.
