Abstract

Ongoing progress in optoelectronic devices necessitates computational tools that self-consistently account for both electronic charge carrier and photon dynamics and interactions. In this paper, we introduce an efficient simulation framework, using the concepts of nonlinear transmission lines, to study fully-coupled charge and photon transport in planar devices. Within the developed framework, the drift-diffusion equations for charge transport are self-consistently coupled with the radiative transfer equation for photon transport and a separate lateral transport model, to obtain a realistic picture of the electro-optical device behaviour. The model allows the detailed study of large-area devices with full access to the wavelength and angle dependent features. It also accounts for photon recycling, providing deeper insight into the complex nature of optical energy transfer and losses in planar multi-layer structures. The efficiency of the framework is illustrated by applying it to study intracavity diode structures, which are intended for exploring high-power electroluminescent cooling in III-V light-emitting diodes.
