A tunable optical comb generator having a source laser configured to generate a continuous wave (CW) light at a first wavelength; and a microresonator coupled to the source laser and configured to receive the CW light and generate an optical signal having a plurality of output wavelengths corresponding to the first wavelength. The generator includes a microresonator tuning device coupled to the microresonator and configured to tune the microresonator to compensate the microresonator for wavelength shifts. A control circuit is coupled to the microresonator tuning device and configured to generate a control signal to control the microresonator tuning device based on the optical signal. Multiple microresonators in the form of microrings may be included to tune the generator. A heater coupled to the microresonators may be used to adjust the microresonators.
