We present a 4-λ × 28-Gb/s/λ silicon ring-resonator-based hybrid-integrated WDM receiver along with the reconfigurable temperature controller. Each of four ring resonators is thermally controlled so that only the target wavelength can be delivered to an integrated photodetector and processed with a hybrid-integrated CMOS TIA. The controller automatically determines the heater voltage required for each ring resonator to receive any target wavelength and maintains this condition against any external temperature fluctuations. It is experimentally verified that the controller performs its task during the initial calibration process and against the thermal stress. In addition, using the controller, WDM channel reconfiguration is successfully demonstrated. |
