Abstract
Results for our fully frequency- und wavevector-dependend self-consistent nonequilibrium Green's function simulations of electron transport through quantum cascade lasers are compared to those from a simplified approach where scattering rates are only evaluated at representative 'typical values' of the in-plane momentum due to the complexity of the underlying many-body problem and the limited computational resources available. We find a noticeable impact on electronic lineshapes.
