Abstract

A simulation method and simulator for a system including a plurality of microring resonators, where the simulation method includes converting the plurality of microring resonators into an equivalent model, generating a virtual system including the equivalent model, inputting an input signal to the virtual system, and outputting an output signal from the virtual system.

A simulation method for a system including a plurality of microring resonators, comprising:

synchronizing a first period, which is a calculation period of a microring resonator (MR) modulator, with a second period, which is a calculation period of the MR switch, wherein the plurality of microring resonators include the MR modulator and the MR switch,
interpolating the first period to match the second period for faster stabilization based on the following equation:

where the τcmd is the first period before the interpolating, the ron is a self-coupling ratio value of an optical coupler included in the microring resonator in an ON state, the βon is a transfer coefficient of a phase shifter included in the microring resonator in the ON state, roff is a self-coupling ratio value of an optical coupler included in the microring resonator in an OFF state, and βoff is a transfer coefficient of a phase shifter included in the microring resonator in the OFF state;
generating an equivalent model corresponding to the plurality of microring resonators based on parameters for the plurality of microring resonators;
generating a virtual system including the equivalent model;
inputting an input signal to the virtual system;
and
outputting an output signal from the virtual system based on the matching first and second periods.
