Abstract

A stabilized optoelectronic oscillator (OEO) with wideband tunability based on an ultra-high-Q silicon microring resonator (MRR) is demonstrated. The stability of the OEO is attributed to the stabilized MRR based on a home-made frequency-stabilization feedback loop. In the experiment, a widely tunable microwave signal range from 0 to 20 GHz is experimentally obtained. The side-mode suppression ratio reaches 52 dB with the frequency jitter of 85 kHz within 10 minutes. The measured phase noise is -95 dBc/Hz at 10 kHz offset frequency when the oscillation frequency is 12.23 GHz.
