Abstract
In the letter 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 IM/DD system. The requirement of laser linewidth is also evaluated. We find that the phase noise has a modest impact on the performance if the laser linewidth is within the requirement. © 1988, The Institution of Electrical Engineers. All rights reserved.
