We analyze in detail the mode-locking characteristics of fiber grating semiconductor lasers using a split-step time-domain approach.数字代码能够描述 FSR 调制频率附近强度调制 (IM) 响应的共振峰谱分裂 (RPSS) 的精细结构，这证明了模拟的准确性，与文献中报告的分析结果非常一致。研究发现锁模 (ML) 频率范围与谐振峰周围的 IM 特征形状密切相关。以不同变迹和色散特性的高斯光栅的ML脉冲特性和频率范围为例。
We analyze in detail the mode-locking characteristics of fiber grating semiconductor lasers using a split-step time-domain approach. The accuracy of the simulations is demonstrated by the capability of the numerical code to describe the fine structure of the resonance peak spectral splitting (RPSS) of the intensity modulation (IM) response near the FSR modulation frequency with a very good agreement with analytical results reported in the literature. The mode-locking (ML) frequency range was found to be closely related to the IM characteristic shapes around the resonance peak. The ML pulse characteristics and frequency range of Gaussian gratings with different apodization and dispersion characteristics have been reported as an example.
