Dynamical properties of quantum dash lasers

We address basic issues related to the dynamical properties of low dimensionality semiconductor lasers. We concentrate on quantum dash lasers but many of the properties hold, with very few changes, to quantum dot lasers. We formulate a self consistent semiclassical model for a multimode laser field which interacts with an inhomogeneously broadened assembly of quantum dashes. The key advantage of this model is the fact that it spectrally resolves the gain and multimode laser field. We show that the differential gain and the nonlinear damping can not be optimized simultaneously.
