Semiconductor quantum optics is on the verge of moving from the lab
to real world applications. When stepping from basic research to
new technologies, device engineers will need new simulation tools
for the design and optimization of quantum light sources, which
combine classical device physics with cavity quantum
electrodynamics. This thesis aims to provide a holistic description
of single-photon emitting diodes by bridging the gap between
microscopic and macroscopic modeling approaches. The central result
is a novel hybrid quantum-classical model system that
self-consistently couples semi-classical carrier transport theory
with open quantum many-body systems. This allows for a
comprehensive description of quantum light emitting diodes on
multiple scales: It enables the calculation of the quantum optical
figures of merit together with the simulation of the spatially
resolved current flow in complex, multi-dimensional semiconductor
device geometries out of one box. The hybrid system is shown to be
consistent with fundamental laws of (non-)equilibrium
thermodynamics and is demonstrated by numerical simulations of
realistic devices.
