我们已经进行了系统的实验和模拟分析产生的增益开关单模激光二极管，无论是自由运行或受到光注入的光频率梳。的模拟已经产生的动力学模型，包括三个速率方程，包括随机噪声项。从实验中提取了模型参数。详尽的模拟和实验的时间分布和光学光谱下产生的开关和光注入条件的广泛范围内进行了比较。在整个范围内的探索的操作条件下发现的优秀的定量协议支持的梳发电机制的分析模型的有效性。生成的详细地图提供了为特定梳特性选择合适的操作条件的指南。
We have performed a systematic experimental and simulation analysis of the optical frequency combs generated by gain-switching single mode laser diodes, either free-running or subjected to optical injection. The simulations have been produced with a dynamical model consisting of three rate equations that include stochastic noise terms. The model parameters have been extracted from experiments. An exhaustive comparison between the simulated and the experimental temporal profiles and optical spectra generated under a wide range of switching and optical injection conditions has been performed. The excellent quantitative agreement found in the entire range of the explored operating conditions supports the validity of the model for the analysis of the comb generation mechanisms. The detailed maps generated provide guidelines for selecting suitable operating conditions for specific comb characteristics.
