摘　　要：本文报导了采用１５５１ｎｍ光栅外腔半导体激光器光源，ＰＩＮ平衡接收机的光频锁相环路的实验研究。相位误差小于３．６°，稳定工作时间大于３０ｍｉｎ。并对ＰＳＫ调制光信号的零差锁相接收进行了初步研究。A 1551nm PIN-diodes balanced optical phase-locked loop, which have external cavity semiconductor lasers as the signal source and the local laser, has been studied. The phase error of the loop is smaller than 3. 6°, steady locked time is longer than 30 minites. With the loop. we have res earched a PSK homodyne receiver.
