Abstract

Quantitative analysis of the impacts of phase noise and shot noise on Phase-Locked Loop（PLL） performances in PSK heterodyne optical communication systems is made in detail.The relationship between PLL optimal bandwidth and laser linewidth and the requirements of bit error rate and bit rate on laser linewidth are obtained.These results are instructive to the design optical PLL.
