A Continuously Tunable Silicon Double-Microring Filter With Precise Temperature Tracking

We demonstrate continuous tuning of a second-order silicon microring filter over the full 7.8-nm FSR of the resonators using the thermo-optic effect. Strongly correlated linear relationships between the heater powers and the filter center wavelength were obtained even in the presence of thermal cros...
