A deterministic quantum dot micropillar single photon source with >65% extraction efficiency based on fluorescence imaging method

Abstract We report optical positioning of single quantum dots (QDs) in planar distributed Bragg reflector (DBR) cavity with an average position uncertainty of ≈20 nm using an optimized photoluminescence imaging method. We create single-photon sources based on these QDs in determined micropillar cavi...
