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.
