A Ring-Resonator-Based Silicon Photonics Transceiver with Bias-Based Wavelength Stabilization and Adaptive-Power-Sensitivity Receiver ratio at the input wavelength of 1286.93nm. The maximum tuning power is 425μW for a resonance range of 0.22nm, which can be leveraged as a fine-control in a dual thermal/bias tuning scheme to improve overall tuning efficiency.

However, reliability and robustness are major challenges to widespread adoption of ring-based silicon photonics. In this work, a CMOS photonic transceiver architecture is demonstrated that incorporates the following enhancements: transmitters with independent dual-edge pre-emphasis to compensate for modulator bandwidth limitations; a bias-based tuning loop to calibrate for resonance wavelength variations; and an adaptive sensitivity-bandwidth receiver that can self-adapt for insitu variations in input capacitance, modulator/p
