    • Ghost branch photoluminescence from a polariton fluid under nonresonant excitation 

      Pieczarka, Maciej; Syperek, Marcin; Dusanowski, Łukasz; Misiewicz, Jan; Langer, Fabian; Forchel, Alfred; Kamp, Martin; Schneider, Christian; Höfling, Sven; Kavokin, Alexey; Sęk, Grzegorz (2015-10-26) - Journal article
      An expanding polariton condensate is investigated under pulsed nonresonant excitation with a small laser pump spot. Far above the condensation threshold we observe a pronounced increase in the dispersion curvature, with a ...
    • Near-unity indistinguishability single photon source for large-scale integrated quantum optics 

      Dusanowski, Łukasz; Kwon, Soon-Hong; Schneider, Christian; Höfling, Sven (2019-05-03) - Journal article
      Integrated single photon sources are key building blocks for realizing scalable devices for quantum information processing. For such applications highly coherent and indistinguishable single photons on a chip are required. ...
    • Relaxation oscillations and ultrafast emission pulses in a disordered expanding polariton condensate 

      Pieczarka, Maciej; Syperek, Marcin; Dusanowski, Łukasz; Opala, Andrzej; Langer, Fabian; Schneider, Christian; Höfling, Sven; Sȩk, Grzegorz (2017-12-01) - Journal article
      Semiconductor microcavities are often influenced by structural imperfections, which can disturb the flow and dynamics of exciton-polariton condensates. Additionally, in exciton-polariton condensates there is a variety of ...
    • Resonance fluorescence from an atomic-quantum-memory compatible single photon source based on GaAs droplet quantum dots 

      Tripathi, Laxmi Narayan; He, Yu-Ming; Dusanowski, Łukasz; Wroński, Piotr Andrzej; Lu, Chao-Yang; Schneider, Christian; Höfling, Sven (2018-07-10) - Journal article
      Single photon sources, which are compatible with quantum memories are an important component of quantum networks. In this article, we show optical investigations on isolated GaAs/Al0.25Ga0.75As quantum dots grown via droplet ...
    • 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 ...
