| 摘 要： | 采用增益开关半导体激光器作为注入种子光源来降低另一个增益开关DFB或Fabry-Perot（FP ）半导体激光器的脉冲抖动.相位噪声测量技术表明：增益开关FP激光器在外部脉冲光注入 下，激光脉冲抖动（均方值）由1.2ps降低至830fs；增益开关DFB半导体激光器在外脉冲注 入下，脉冲抖动由12ps降低至1.8ps.

| Abstract: | A gain-switched laser diode (LD) was used as an external pulse injection source to reduce the timing jitter of gain-switched Fabry-Perot and DFB LDs. The low j itter and frequency-independent optical pulse can be achieved using this techniq ue. Phase noise measurement shows that with external pulse injection, the timing jitter of gain-switched FP LD was reduced from 1.2ps to 830fs and the timing ji tter of gain-switched DFB was reduced from 12ps to 1.2ps. |
