Multi-species modeling of quantum dot lasers with microscopic treatment of coulomb scattering

We present a spatially resolved semiclassical model for the simulation of semiconductor quantum-dot (QD) lasers including a multi-species description for the carriers along the optical active region. The model links microscopic determined quantities like scattering rates between the different species and dephasing times, that depend essentially on the carrier densities, with macroscopic transport equations and equations for the optical field.
