Abstract :
Novel approaches to obtain compact, high-speed, low-voltage modulators using circular microresonators are presented. Two different mechanisms, free carrier injection and depletion width modulation are considered. Frequency 3 dB bandwidths of over 8 GHz are achieved at modulation voltages less than 1V.
