    (a) Dint of TE00 mode with different ring widths; (b) Difference between the resonant frequency of TE00 and TE10 with different ring widths
    (a) Scanning electron microscopy(SEM) of the overall structure of the microring; (b) SEM of the coupled positions of the waveguide and microring; (c) SEM of the sidewall of the waveguide tilted 30°
    (a) Transmission spectrum of the TE00 and TE10 in the wavelength range from 1540 nm to 1570 nm; (b) Zoomed-in region of the two close resonances near 1550 nm
    Transmission spectrum of TE00 and TE10 near 1550 nm at different powers (20-430 mW)
    When the pump power is 350 mW, (a) the spectral evolution process from i to v is obtained by increasing the pump wavelength; (b) Schematic of the power of pump transmission; (c) Measurements of the beat frequency noise of the two soliton combs and the MI state comb, and the background noise of PD
