Optical soliton crystal optical frequency comb generation system and method based on micro-ring resonator

Abstract

In view of the demand of microwave photonics, astronomical spectrometric measurement and parallel optical fiber communication systems for a high-frequency spaced optical frequency comb source, especially the demand for an optical frequency comb source which can be integrated on a chip, the invention provides an optical soliton crystal optical frequency comb generation system and method based on amicro-ring resonator. The system includes a pump laser, an optical amplifier, a polarization controller, an optical frequency comb generator and a temperature controller which are sequentially connected through a single-mode optical fiber. The output wavelength of the pump laser is in accordance with the wavelength of a required optical frequency comb, and the operating wavelength of the optical amplifier is in accordance with the output wavelength of the pump laser. The polarization controller is a polarization controller which can withstand the power of the pump light signal. The optical frequency comb generator includes a package shell, a micro-ring resonator and a temperature regulator. The micro-ring resonator and the temperature regulator are packaged in the package shell. The working temperature of the micro-ring resonator is controlled by the temperature controller which is set outside the package shell and connected with the temperature regulator. The optical soliton crystal optical frequency comb generation system has the advantages of low cost, high reliability and small size.
