Abstract
Modeling of quantum cascade lasers requires precise determination of the emission frequency and current density for which the electronic band structure must be accurately solved. In this work, we explore the effect of the fourteenth-order k·p conduction band nonparabolicity and interface broadening due to inter-diffusion and fluctuations of the band edges on the electronic structure and Rabi-coupling oscillation frequency of a THz quantum cascade laser.
