Systematic investigation of coupling-modulated microring resonators based on interleaved p-n junctions

We systematically investigate the optical effects and the optical functions of coupling-modulated microring resonators (CMR) based on interleaved p-n junctions. The optical effect of coupling-induced frequency shifts (CIFS) is firstly observed experimentally. Due to the CIFS and thermal-optical effect, the resonance spacing is tuned as large as 0.182 nm (corresponding to 22.8 GHz), the extinction ratio is continuously modulated between 0 dB to as large as 35 dB.
