Abstract

A microscopic theory is used to study the optical absoprtion and gain spectra of semiconductor quantum dots. The dephasing of a coherent excitation and line‐shifts of the interband transitions due to carrier‐carrier Coulomb interaction and carrier‐phonon interaction are determined from a quantum kinetic treatment of correlation processes. Our theoretical model predicts a new phenomenon in quantum‐dot systems, namely a reduction of the optical gain with increasing carrier density.
