GS-DFB半导体激光器的光自注入技术
A Novel Technique of Self-seeding of GS-DFB Laser
摘要
报道了一种光脉冲自注入的新方法,它能使增益开关DFB激光器输出光脉冲的时间抖动从5.7 ps减小到1.2 ps,分析了注入光延迟时间及功率对时间抖动的影响,指出为取得抑制时间抖动的最佳效果, 必须选择合适的反馈光脉冲延迟时间和适当的反馈光功率。实验中观察到在增益开关DFB激光器光脉冲建立期间注入反馈光时,输出光脉冲会发生严重畸变。
Abstract
A novel, simple self-seeding technique to reduce timing jitter of a GS-DFB laser is proposed. Using this technique, the pulse time jitter is reduced from 5.7 ps to 1.2 ps. The variations of timing jitter under different self-seeding optical power and delay time are measured in the experiment. Both appropriate feedback optical power and delay time are strictly required to suppress the pulse time jitter. When the self-seeding light is injected during turn-on time of GS-DFB laser diode, serious distortion of optical pulses is observed.
