摘　　要：提出了一种基于级联电吸收调制器(EAM)和相位调制器(PM)的多载波光源发生器方案。对比分析了基于单个EAM级联PM的多载波光源发生器与基于两个EAM级联PM的多载波光源发生器产生的多载波光源,利用基于两个EAM级联PM的多载波光源发生器实现了频率间隔为15GHz、平坦度在0.1dB范围内的19个子载波的多载波光源。同时研究了EAM的调制指数和啁啾因子、PM的驱动信号幅度以及调制器驱动信号的相位差等参数对产生多载波光源的影响。A new method for multicarrier optical source generator based on cascaded electro-absorption modulator （EAM） and phase modulator （PM） is proposed. The multicarrier optical source based on single EAM cascaded PM and the multicarrier optical source based on two EAM cascaded PM are studied and analyzed respectively. Multicarrier optical source with frequency interval of 15 GHz, and 19 subcarriers in the range of 0.1 dB flatness using multicarrier optical source generator based on two EAM cascaded PM are achieved. Meanwhile, the influence of the parameters such as modulation index and chirped factor of EAM, modulation signal amplitude of PM, and phase difference of modulators on the multicarrier optical source are also analyzed.
