Abstract
A global quantum simulation—steady state as well as ultrafast—of non-equilibrium carrier dynamics in semiconductor-based quantum-cascade lasers is presented. In particular, the interplay between phase coherence and energy-relaxation/dephasing processes is investigated and discussed. Our analysis shows that quantum corrections to the semiclassical scenario are minor and confirms the incoherent nature of steady-state charge transport in these structures.
