Abstract
This paper presents an automatically calibrated and tuned microwave silicon photonic ring resonator. Due to process variations, the initial response of the ring resonator is severely distorted. By embedding a tunable coupler (Mach-Zehnder interferometer (MZI)) and a photo-detector (PD)-based monitor within the ring, and developing a proper automatic tuning algorithm, the desired microwave frequency response of the ring with free spectral range (FSR) of 50 GHz is reconstructed and its resonance frequency is tuned. RF measurements show cancellation of10 and 20 GHz signals by tuning the ORR.
