Abstract
The performance of a coherent heterodyne AM-DSB optical receiver is evaluated by taking into account the phase noise of both the transmitter and local lasers. The results show that the performance of the coherent AM-DSB system is about 20 dB superior to that of the conventional intensity modulation/direct detection system The requirement of laser linewidth is also evaluated. The authors find that the phase noise has a modest impact on the performance if the laser linewidth is within the requirement
