Abstract

This paper presents the resonance response analysis of a photonic microring resonator. It covers the mathematical as well as simulation analysis on the modulated signals. The mathematical formulation provides a relation of several microring resonator parameters that could potentially affect the ring resonator performances. The simulation shows a graphical representation of the ring resonator full-width at half-max, quality factor (Q-factor) as well as the depth of the resonance at different modulation voltages applied to the ring. Several parameters have also been altered which is the ring radius, the coupling coefficient of the waveguides as well as the waveguide material group index. With this investigation, we determine the possible cause of the change in Q factor of a silicon microring resonator when the resonance is modulated and the possible solution to minimize the problem.
