Electroluminescent (EL) cooling of semiconductors has received increasing attention in recent years. To optimize the performance of devices intended for EL cooling, special care is needed in minimizing electrical losses resulting from e.g. potential barriers, and optical losses resulting from e.g. parasitic absorption. In this work, we introduce and explore a full-device modeling tool for arbitrary planar photonic devices by coupling together the interference-exact radiative transfer equation (IFRTE) of photon transport and drift-diffusion (DD) equations of carrier transport. The IFRTE coupled with DD represents a fully self-consistent model of lossy wave optics and carrier transport, connecting emission and photon recycling with electron and hole dynamics. We deploy the model to study and optimize photon emission and absorption as well as photocarrier collection in double-diode structures for EL cooling.
