Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For the step numbers in the following embodiments, it is only set for the convenience of illustration and description, and the order between the steps is not limited in any way. The execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art sexual adjustment.
[0026] A soliton frequency comb self-generation method based on a negative thermo-optic coefficient chalcogenide microcavity, comprising:
[0027] The tunable optical device emits the pump light with a preset wavelength and power, and after the power is adjusted by the fiber amplifier, it is input to the polarization controller. The design polarization mode is consistent, and the pump light is controlled to enter the negative thermo-optic coefficient microring resonator through the tunable optical attenuator;
