Soiton state and chaotic state microcavity optical frequency comb generation system and control method

The invention discloses a soliton state and chaotic state microcavity optical frequency comb generation system and a control method. The system comprises a light path part, a spectrum detection part and a control part, and the light path part comprises a narrow linewidth laser, an optical amplifier, a filter, a micro-ring resonator, a fiber bragg grating and a light detector which are connected in sequence. Optical splitters are arranged between the filter and the micro-ring resonator, between the micro-ring resonator and the fiber bragg grating and between the fiber bragg grating and the optical detector; the spectrum detection part comprises a spectrograph; the spectrograph is connected with an optical splitter between the micro-ring resonator and the fiber bragg grating; and the control part comprises an acquisition card, an optical detector connected with the acquisition card, a narrow linewidth laser and a power supply. The single soliton state and chaos state micro-cavity optical frequency comb can be r
