We derive the frequency-dependent modulation transfer functions for microring resonator modulators, using a small-signal analysis. Modulation efficiencies are obtained in terms of familiar optical cavity parameters, which provide an intuitive understanding of device performance. The results are in good agreement with experimental data, and are used to compare operating characteristics between resonance-modulated and coupling-modulated microresonators.
