Microscopic theory of cavity-enhanced single-photon emission from optical two-photon Raman processes

Year: 2018

Type: article

Abstract: During the last two decades, single-photon emission from two-photon Raman processes has been extensively studied both experimentally and theoretically in atomic as well as in quantum-dot multilevel systems. However, despite theoretical predictions on-demand emission, which is crucial for quantum networking, has not been achieved in experiments yet. Based on the cluster-expansion approach, the authors have performed an in-depth microscopic analysis of the Raman transition in fundamental three-level configurations. They find that excitation-induced destructive quantum interference and Stark shifts of the Raman resonance have to be taken into account in order to close in on on-demand single-photon emission.
