Abstract

The invention provides an optical frequency comb generator based on silicon nitride. The optical frequency comb generator comprises a reflector surface, a gain medium, a filter, a generator, and a controller which are arranged successively, wherein the generator is used for generating an optical frequency comb; the controller is connected to the gain medium and the filter; the reflector surface isused for reflecting laser light from a pumping source; the gain medium is used for amplifying the reflected laser light; the filter outputs the laser light to the generator; and the generator is a silicon nitride device. The optical frequency comb generator based on silicon nitride can greatly simplify the system complexity of the optical frequency comb and reduce the cost by using a silicon nitride chip.

Description

technical field [0001] The invention relates to an optical frequency comb generator, in particular to an optical frequency comb generator based on silicon nitride. Background technique [0002] An optical frequency comb (OFC) refers to a spectrum composed of a series of frequency components that are evenly spaced and have a coherent and stable phase relationship on the spectrum. With the rapid development of optical communication technology, OFC has attracted more and more scholars' attention due to its wide application in the fields of optical arbitrary waveform generation, multi-wavelength ultrashort pulse generation and dense wavelength division multiplexing. [0003] In principle, an optical frequency comb behaves as an optical frequency sequence with equal frequency intervals in the frequency domain, and as an electromagnetic field oscillation envelope with a femtosecond time width in the time domain. The time width of the slowly varying envelope satisfies the Fourier ...
