Optical frequency comb, consisting of many coherent lines spaced with equal frequency separation, is a new type of light source. This paper presents the optical frequency comb generation techniques including electro-optic modulation and nonlinear microresonator, and demonstrates its application and prospects in microwave photonic signal generation, conversion and receiving.
