Optical frequency comb in silicon nitride microresonator(Invited)
Fig. 1. Conceptual representation of the optical loss in the microresonator at low power
Fig. 2. (a) Schematic diagram of the silicon nitride microring resonator before redeposition of film, silica protective layer has been deposited above the coupling waveguide; (b) Side view of the silicon nitride microring resonator with the redeposited film
Fig. 3. (a) Statistical histograms of intrinsic
Fig. 4. (a) Transmission spectrum of the TM mode in the silicon nitride microring resonator; (b) The change of the intracavity power and the transmitted power with the pump light sweeping from the blue detuning to the red detuning, where distinct soliton steps can be observed; (c) The generated spectral spectrum of the soliton microcomb, the envelope perturbation is caused by avoided mode crossings; (d) The spectral spectrum of the soliton microcomb and the corresponding integrated dispersion curve, the dispersion abrupt change on the dispersion curve corresponds to the envelope perturbation on the soliton microcomb spectrum
