摘要

提出了一种主动谐波锁模光纤环形激光器，它由两个半导体光放大器组成，一个称为调制型光放大器，另一个称为增益型光放大器。该模型考虑了材料增益曲线、载流子空间分布和宽带自发噪声发射。理论研究和数值模拟结果表明，可以获得7.5ps的稳定锁模脉冲串，重复频率为20GHz，脉冲串的波长在40nm调谐范围内。

Numerical study of an actively harmonic mode-locked fiber ring laser with SOAs

An actively harmonic mode-locked fiber ring laser is presented in this paper, It consists two semiconductor optical amplifiers (SOAs), one is named modulation SOA, the other is named gain SOA. The material gain profile, spatial distribution of carriers and the broad-band spontaneous noise emission are considered in the model. The results of theoretical study and numerical simulations reveal that 7.5ps stable mode-locked pulse trains with repetition rate of 20GHz can be obtained, and the wavelength of pulse trains are over 40nm tuning range.
