Recent Progress and Applications on Fiber-based Optical Frequency Comb
Invented at the turn of the century,Optical frequency comb has coherently bridged between radio frequencies and optical frequencies.With more than 20-years continuous development,optical frequency comb has revolutionized optical frequency measurement methods and been widely used in precision measurement beyond that.Firstly,the advantages of the fiber optical frequency comb are highlighted,and the technical principle of the fiber optical frequency comb is briefly introduced.Then,the main development directions of the fiber optical frequency comb,namely low noise,high power,and integration,are analyzed.Finally,the application progress of the fiber optical frequency comb in optical frequency measurement,absolute distance measurement,ultra-low noise microwave generation,precise spectral measurement,and astronomical spectral calibration are discussed.
