Abstract

We report our latest experimental and numerical work on silicon microresonator passive and electro-optic active devices. On the passive device front, we demonstrate an electrically tunable silicon microring notch filter for converting 3.6-Gbps non-return-to-zero (NRZ) data format to return-to-zero (RZ)-like data format. We show that the converted RZ-like data quality highly depends on the notch filter extinction ratios. On the active device front, we demonstrate a silicon microring modulator using a double-coupled U-bend waveguide as a feedback and a pair of laterally integrated injectiontype p-i-n diodes for bias/signal modulation. We show that the microring modulator extinction ratios are electrically controlled by applying a DC-bias across either the feedback-waveguide or the microring while applying a modulation signal across the other p-i-n diode. We also propose silicon microdisk modulators with selectively integrated depletiontype Schottky diodes. Our numerical simulations suggest that the microdisk structures can be advantageous compared with microring structures. We show that electrical rise time on the order of a few ps is feasible using microdisks. We also allude to on-going work on extending the microresonator devices discussed here to building functional silicon optoelectronics integrated circuits.
