摘要
利用电吸收调制器(Electro-absorption Modulator, EAM)和频率调制器(Frequency Modulator, FM)的级联结构，提出了一种新型光学频率梳(Optical Frequency Comb, OFC)产生方案。本方案结构简单、易于控制，输出噪声低。对提出的方案原理进行了理论分析，并利用Optisystem7.0 软件进行仿真研究。仿真结果表明：产生了平坦的光学频率梳，其中心波长和谱线间距均可独立调谐。产生的OFC 有效带宽为3.8 nm，得到了谱线间距为5 GHz 的105条谱线。
Abstract
Using the cascade structure of an Electro-absorption Modulator (EAM) and a frequency modulator (FM), we proposed a new Optical Frequency Comb (OFC) generation scheme. The program structure is simple, easy to be controlled and the output noise is low. We conducted a theoretical analysis on the principle scheme and did research on the simulation with software of Optisystem7.0. The simulation results show that: we generated a flat optical frequency comb, whose center wavelength and line spacing can be tuned independently. Also，the effective bandwidth of the OFC is 3.8 nm, its line spacing is 5 GHz and number of lines is 105.
