Abstract
Based on an equation of motion approach we present a theoretical framework to calculate the luminescence and absorption of semiconductor quantum dot systems for weak incoherent pumping and coherent optical excitation. In this contribution the following topics are covered: starting with incoherently driven quantum dots, first non- Lorentzian emission line shapes are investigated. Second, we discuss the temperature dependant generation of polarization-entangled photon pairs in a biexciton cascade. Next, Raman signatures and phonon-assisted Mollow triplets in the luminescence spectra of coherently driven quantum dots in the strong excitation regime are considered. Finally, we focus on multi-phonon and multi-photon processes in a quantum dot microcavity system.
