    • Deterministic coupling of quantum emitters in WSe2 monolayers to plasmonic nanocavities 

      Iff, Oliver; Lundt, Nils; Betzold, Simon; Tripathi, Laxmi Narayan; Emmerling, Monika; Tongay, Sefaattin; Lee, Young Jin; Kwon, Soon Hong; Höfling, Sven; Schneider, Christian (2018-09-20) - Journal article
      We discuss coupling of site-selectively induced quantum emitters in exfoliated monolayers of WSe2 to plasmonic nanostructures. Gold nanorods of 20 nm-240 nm size, which are arranged in pitches of a few micrometers on a ...
    • Exciton dynamics in solid-state green fluorescent protein 

      Dietrich, Christof P.; Siegert, Marie; Betzold, Simon; Ohmer, Jürgen; Fischer, Utz; Höfling, Sven (2017-01-27) - Journal article
      We study the decay characteristics of Frenkel excitons in solid-state enhanced green fluorescent protein (eGFP) dried from solution. We further monitor the changes of the radiative exciton decay over time by crossing the ...
    • Observation of bosonic condensation in a hybrid monolayer MoSe2-GaAs microcavity 

      Waldherr, Max; Lundt, Nils; Klaas, Martin; Betzold, Simon; Wurdack, Matthias; Baumann, Vasilij; Estrecho, Eliezer; Nalitov, Anton; Cherotchenko, Evgenia; Cai, Hui; Ostrovskaya, Elena A.; Kavokin, Alexey; Tongay, Sefaattin; Klembt, Sebastian; Höfling, Sven; Schneider, Christian (2018-08-16) - Journal article
      Bosonic condensation belongs to the most intriguing phenomena in physics, and was mostly reserved for experiments with ultra-cold quantum gases. More recently, it became accessible in exciton-based solid-state systems at ...
    • Room temperature Tamm-Plasmon exciton-polaritons with a WSe2 monolayer 

      Lundt, Nils; Klembt, Sebastian; Cherotchenko, Evgeniia; Betzold, Simon; Iff, Oliver; Nalitov, Anton V.; Klaas, Martin; Dietrich, Christof P.; Kavokin, Alexey V.; Höfling, Sven; Schneider, Christian (2016-10-31) - Journal article
      Solid state cavity quantum electrodynamics is a rapidly advancing field which explores the frontiers of light-matter coupling. Metal-based approaches are of particular interest in this field, since they carry the potential ...
    • Spontaneous emission enhancement in strain-induced WSe2 monolayer-based quantum light sources on metallic surfaces 

      Tripathi, Laxmi Narayan; Iff, Oliver; Betzold, Simon; Dusanowski, Łukasz; Emmerling, Monika; Moon, Kihwan; Lee, Young Jin; Kwon, Soon Hong; Höfling, Sven; Schneider, Christian (2018-05-16) - Journal article
      Atomic monolayers of transition metal dichalcogenides represent an emerging material platform for the implementation of ultracompact quantum light emitters via strain engineering. In this framework, we discuss experimental ...
    • Three-dimensional photonic confinement in imprinted liquid crystalline pillar microcavities 

      Dusel, Marco; Betzold, Simon; Brodbeck, Sebastian; Herbst, Stefanie; Würthner, Frank; Friedrich, Daniel; Hecht, Bert; Höfling, Sven; Dietrich, Christof P. (2017-05-19) - Journal article
      We demonstrate the feasibility of a thermal imprint technology capable of structuring organic thin films with liquid crystalline properties forming feature sizes on a several micrometer scale. The imprint technique can ...
    • Tunable light-matter hybridization in open organic microcavities 

      Betzold, Simon; Herbst, Stefanie; Trichet, Aurélien A. P.; Smith, Jason M.; Würthner, Frank; Höfling, Sven; Dietrich, Christof (2018-01-17) - Journal article
      Open microcavities represent a versatile cavity design that allows the external control of internal properties such as cavity thickness and mode detuning without changing the key parameters of the cavity itself, rendering ...
