Archivio Istituzionale della RicercaA review of the most advanced microscopic treatments of optoelectronic quantum devices is presented. After recalling the fundamentals of carrier coherence versus energy relaxation/dephasing, we shall discuss a number of simulated experiments for two different regimes: coherent ultrafast excitation and steady-state conditions. We shall finally introduce a fully non-diagonal treatment of the problem, which shows that also in steady-state conditions one deals with a residual single-particle phase coherence, resulting in a scattering-induced state renormalization.

Abstract
A review of the most advanced microscopic treatments of optoelectronic quantum devices is presented. After recalling the fundamentals of carrier coherence versus energy relaxation/dephasing, we shall discuss a number of simulated experiments for two different regimes: coherent ultrafast excitation and steady-state conditions. We shall finally introduce a fully non-diagonal treatment of the problem, which shows that also in steady-state conditions one deals with a residual single-particle phase coherence, resulting in a scattering-induced state renormalization.
