A REVIEW: OPTICAL FREQUENCY COMB GENERATOR (OFCG)

With the recent breakthrough in the field of optical frequency measurement and synthesis, it is now possible to accurately measure the frequency of optical frequency signals, generate arbitrary waveform light pulses and perform accurate optical frequency synthesis. Generating precise optical freq uencies with a functional power is necessary in many fields of science and technology. This paper reviews different methods for generating the optical frequency comb generator (OFCG). This article highlights the different mechanisms integral to the operati on of the pulsed laser and the tailored optical fiber. It also presents the techniques that enable the promised frequency synthesis and measurement. Three different techniques discussed in this paper which is 1) EO Phase Modulator, 2) Mode locked Laser and 3) Fiber Ring based Comb generator
