Paper Abstract

An efficient split-step time-domain modeling method is developed for the simulation of pulse propagation characteristics through all-pass and add/drop filters made of ring resonators. The bus and ring waveguides are divided into several sections of equal size and the phase and coupling is updated during each time step corresponding to the propagation time over a section. The pulse propagation dependence on the coupling ratio of the all-pass and add/drop filters is investigated. It is shown that very large scale ring resonator devices such as cascaded add/drop filters can be very efficiently modeled in time domain.
