Paper Abstract

The development of optical amplifiers for signal transmission over transoceanic distances has opened up a new horizon in photonics towards the practical realisation of extremely fast and ultra long haul and wide band transmission systems, particularly so, when the high performance coherent detection systems are used. In this paper, the performance behaviour of coherent optical binary and Multilevel FSK signalling schemes employing optical amplifiers is analysed by accounting for the laser phase noise of the transmitter and local oscillator lasers in addition to the noise of the receiver and the multiple amplifiers. The results are compared with the case when the phase noise is assumed to be absent. Further, the performance of PSK systems are compared with those of their PSK counterparts.
