Microscopic density matrix model for optical gain of terahertz quantum cascade lasers : many-body, nonparabolicity, and resonant tunneling effects
Intersubband semiconductor-Bloch equations are investigated by incorporating many-body Coulomb interaction, nonparabolicity, and coherence of resonant tunneling transport in a quantitative way based on the density matrix theory. The calculations demonstrate the importance of these parameters on opti...
