A time-domain optical add-drop multiplexing (OADM) technology using microring resonators is reported. Design and simulation are presented. The microring resonator is predicted to be fabricated by using Pockler electro-optic materials. The microring resonators possess a multistage-cascaded structure to satisfy the requirement to generate switching windows. Cascaded coupled microring resonator can expand the single resonant point into a box-like resonant region and reduce the wings of resonant curve. While multistage resonators are used and a certain shift of the resonant region is arranged between the stages, the total resonant region can be expanded further. We achieve the shift of the resonant region between the two stages by selecting different ring radii. The resulted microring resonators possess a box-like characteristic with shape wings. The OADM includes two microring resonators (MMRs) driven by sine wave voltages, one is used to accomplish the add function the other is used to accomplish the drop function. The only operation differences between the two MMRs are the bias voltage and the phase of the driving signal. The OADM only requires electrical control signal and simple structure instead of high-quality optical control pulse and interferometer structure. FDTD simulation results show that the resonators can stratify the requirements to generate complementary switching windows for OADM operation.
