To predict the optical properties of semiconductor laser structures, a microscopic treatment of the carrier dynamics is essential. We calculate the dynamics of semiconductor laser structures, fully including carrier-carrier as well as carrier-LO phonon scattering effects. The dynamics depends on parameters such as the excitation energy and intensity. We discuss the detailed dynamics which can only be modelled microscopically as well as the validity of simple rules of thumb for scattering rates and temperature of injected carriers.
