摘要
本文研究了光锁相环(OPLL)本振的相位传递函数(PTF)在非理想情况下,OPLL的噪声性能,指出:在这种情况下,存在最佳环路带宽,可使噪声方差达到最小。同时,也研究了弱光反馈对OPLL噪声性能的影响。
The performance of optical phase-locked loop (OPLL) and theeffects of weakly optical feedback on the performance of OPLL are pre-sented with non-ideal phase transfer function for the local oscillator. Thephase noise variance of OPLL can be minimum with suitably selecting theloop natural frequency.
