Dynamics and Frequency Response of Microring-Based Optical Modulator Considering Nonlinear Effects

In this paper, we analyze dynamics and frequency response of GaAs-based microring modulators at the 1.55 μm using the finite-difference time-domain method. Two types of modulation are investigated: pump-probe configuration and modulation of the coupling coefficient. The pump-probe signals are tuned...
