Abstract

Semiconductor quantum dots (QDs) are promising candidates for applications in quantum communication and quantum computing as they show emission of single, indistinguishable photons. Since the QDs are embedded in a semiconductor environment, the extraction efficiency is firmly limited due to the high refractive index contrast at the air interface. As high brightness of the single-photon source is crucial for the aforementioned applications, various mechanisms for enhancing the extraction efficiency of QDs are under current investigation, using either broadband approaches or narrow band cavity quantum electrodynamic systems.
