Effects of non-parabolicity and band-warping of the energy dispersion are entered in a quantumwell laser simulator (MINILASE-II), which self-consistently solves Schödinger's equation,Poisson's equation, the drift diffusion equations, and the photon rate equations. An eightband k.p model is used to determine the electronic band structure for a strained-layerIn.2Ga.8As/Al.1Ga.9As system. The k.p calculation is performed independently of the lasersimulator, and exported to MINILASE-II in the form of a density of states and an energydependentaveraged momentum matrix element. The results obtained for the gain and modulationresponse are compared to those obtained from a parabolic band model with a constantmatrix element
