摘要
对设有内置式RF电路的分布反馈(DFB)半导体激光器在增益开关工作状态下出现反常光谱的原因进行了分析.分别对该激光器在正常工作(即小信号驱动)和增益开关(即大信号驱动)情况下的时域和频域输出结果进行了对比和分析,研究发现内置式RF电路的瞬态失效是导致增益开关DFB激光器产生多波长光谱的原因.
The abnormal spectrum phenomenon of distributed feedback (DFB) laser embedded with RF circuit generates under gain-switching operation was analyzed. Time-domain and frequency-domain output of the laser with normal condition (small signal driving) and gain-switched condition (larges signal driving) ,were compared and respectively analyzed. The results show that instantaneous invalidation of the DFB laser under gain-switching operation directly causes multi-wavelength spectrum phenomenon.
