Strain-free, monodisperse, and spatially sparse local-droplet-etched (LDE) QDs have recently been demonstrated as a superior alternative to traditional Stranski-Krastanov QDs. However, integration of LDE QDs into nanophotonic architectures with the ability to scale to many interacting QDs is yet to be demonstrated. We present a potential solution by embedding isolated LDE GaAs QDs within an Al0.4Ga0.6As Huygens’ metasurface with spectrally overlapping fundamental electric and magnetic dipolar resonances. We demonstrate for the first time a position- and size-independent, 1 order of magnitude increase in the collection efficiency and emission lifetime control for single-photon emission from LDE QDs embedded within the Huygens’ metasurfaces. Our results represent a significant step toward leveraging the advantages of LDE QDs within nanophotonic architectures to meet the scalability demands of photonic QIS. date: 2024 date_type: published publisher: AMER CHEMICAL SOC official_url: http://dx.doi.org/10.1021/acs.nanolett.3c04846 full_text_type: other language: eng verified: verified_manual elements_id: 2270739 doi: 10.1021/acs.nanolett.3c04846 medium: Print-Electronic lyricists_name: Mitrofanov, Oleg lyricists_id: OMITR95 actors_name: Mitrofanov, Oleg actors_id: OMITR95 actors_role: owner funding_acknowledgements: [Basic Energy Sciences]; DE-NA0003525 [U.S. Department of Energy, Office of Basic Energy Sciences, Division of Materials Sciences and Engineering]; [U.S. Department of Energy's National Nuclear Security Administration] full_text_status: restricted publication: Nano Letters volume: 24 number: 16 pagerange: 4749-4757 pages: 9 event_location: United States citation: Iyer, PP; Prescott, S; Addamane, S; Jung, H; Renteria, E; Henshaw, J; Mounce, A; ...
