“…We assumed a Thévenin resistance of 50 Ω. With the results presented in Table I, [29] and Fig. 11, we can now verify whether the usual description based on the quality factor is accurate [1].…”

“…To that extent, we showed in a previous work [29] with the microring described in Table I, that the contribution of the p-n junction to the total bandwidth is significant and cannot be neglected. In fact, for this particular case, the sole optical model yields a bandwidth around 43.1 GHz, whereas the combined model yields a bandwidth of 32.5 GHz.…”

We propose an analytical, time domain model for microring and microdisk modulators which considers both their electrical and optical properties. Theory of the dynamics of microring/microdisk is discussed, and general solutions to the transfer matrix representation are presented. Both static and dynamic predictions from the model are compared to measurement results to demonstrate the accuracy of our model. Static predictions and measurements are presented for power and phase responses whereas dynamic predictions and measurements are presented for small-signal and large-signal operations. The model verifies that the chirping and modulation bandwidth of the modulators depend on the detuning state. Finally, the accuracy and scalability of several techniques employed in the model are discussed.
