Abstract
A model based on a full travelling-wave analysis of a semiconductor laser amplifier is applied to calculate the increase in spectral linewidth of an unmodulated optical carrier passing through the amplifier. This linewidth can then be used in system performance calculations for a coherent optical transmission system employing laser amplifiers along the fibre link.Keywords
