Simulation of quantum light sources using the self-consistently coupled Schrödinger-Poisson-Drift-Diffusion-Lindblad syste

摘要

The device-scale simulation of electrically driven quantum light sources based on semiconductor quantum dots requires a combination of the (classical) semiconductor device equations with cavity quantum electrodynamics. In this paper, we extend our previously developed hybrid quantum-classical model system – where we have coupled the drift-diffusion system with a Lindblad-type quantum master equation – by including a self-consistent Schrödinger–Poisson problem. The latter describes the (quasi-)bound states of the quantum dot carriers. The extended model allows to describe the bias-dependency of the emission spectrum due to the quantum confined Stark effect.
