Characterization of Thermally Controlled Silicon Nitride Microring Resonator for the Generation of Optical Frequency Combs

We investigate a thermally controlled silicon nitride microring resonator with anomalous dispersion for the generation of single- and dual-pumped optical frequency combs. Besides, the Kerr microresonator has been characterized by alternating the pump power and heater voltage. We also demonstrate the conditions of heater voltage to generate single-pumped optical parametric oscillation and then the transition to frequency combs. Moreover, the voltage-controllable single- and dual-pumped parametric conversion, including single-and dual-pumped Kerr comb generation, is then characterized.
