F. Oyafuso et al., GAIN CALCULATION IN A QUANTUM-WELL LASER SIMULATOR USING AN 8 BAND K-CENTER-DOT-P MODEL, VLSI design (Print), 6(1-4), 1998, pp. 367-371
Effects of non-parabolicity and band-warping of the energy dispersion
are entered in a quantum well laser simulator (MINILASE-II), which sel
f-consistently solves Schodinger's equation, Poisson's equation, the d
rift diffusion equations, and the photon rate equations. An eight band
k . p model is used to determine the electronic band structure for a
strained-layer In.2Ga.8As/Al.1Ga.9As system. The kp calculation is per
formed independently of the laser simulator, and exported to MINILASE-
II in the form of a density of states and an energy dependent averaged
momentum matrix element. The results obtained for the gain and modula
tion response are compared to those obtained from a parabolic band mod
el with a constant matrix element.
