Combined metallic nano-rings and solid-immersion lenses for bright emission from single InAs/GaAs quantum dots
Oliver Joe Trojak, Christopher Woodhead, Suk-In Park +3
Solid-state single-photon emitters are key components for integrated quantum photonic devices. However, they can suffer from poor extraction efficiencies, caused by the large refra…
Direct observation of nanofabrication influence on the optical properties of single self-assembled InAs/GaAs quantum dots
Jin Liu, Kumarasiri Konthasinghe, Marcelo Davanco +11
Single self-assembled InAs/GaAs quantum dots are a promising solid-state quantum technology, with which vacuum Rabi splitting, single-photon-level nonlinearities, and bright, pure,…
Metallic nanorings for broadband, enhanced extraction of light from solid-state emitters
Oliver J. Trojak, Suk In Park, Jin Dong Song +1
We report on the increased extraction of light emitted by solid-state sources embedded within high refractive index materials. This is achieved by making use of a local lensing eff…
Cryogenic photoluminescence imaging system for nanoscale positioning of single quantum emitters
Jin Liu, Macelo Davanco, Luca Sapienza +5
We report a photoluminescence imaging system for locating single quantum emitters with respect to alignment features. Samples are interrogated in a 4~K closed-cycle cryostat by a h…
