基于级联频率调制器获取宽带微波频率梳的研究

new type of cascading structure based on laser and frequency modulator is proposed to obtain a broadband microwave frequency comb.Simulation analysis was carried out using optisystem, an optical communication design software,the effects of changes in the optical power,the frequency offset, and the modulation frequency on the generated signal are discussed separately.The numerical simulation results show that it is reasonable settimg parameters can obtain a signal with ten spectral lines .The signal has a bandwidth of320 GHz andequal comb spacing.
