| 摘 要： | 本文在理论上研究了由于外部光反馈引起的半导体激光器的相位噪声.理论分析是通过引入一个反馈耦合率K和线性化速率方程,导出了半导体激光器相位噪声功率谱密度的表达式.这表明相位噪声功率谱密度随外腔长度而周期性地漂移,且功率谱密度的峰值随外部反馈耦合率而发生很大的变化.

| Abstract: | Phase noise in semiconductor laser due to external optical feedback is investigated theoretically. The theoretical analysis introduces a feedback coupling rate K and linearized rate equations. We also derive the experssion of phase noise power spectrum density of semiconductor laser. It is shown that the phase noise spectrum density shift periodicity with the length of external cavity and the peak value of power spectrum density varies considerably with the feedback coupling rate. |
