Abstract
We study by means of stochastic rate equations the effects that an int ensity dependent linewidth enhancement factor produces on the spectral properties of the output from a single-mode semiconductor laser durin g the transient regime following its gain-switching. For an increasing intensity dependence, the power spectrum broadens and shifts towards higher frequencies, with an increase in the pulse-to-pulse spectral va riations. These effects degrade the performance of fiber-based, pulse- code-modulated optical communication systems.
