Tomoyuki Horikiri,Makoto Yamaguchi,Kenji Kamide,Yutaka Shikano,Yasuhiro Matsuo,Tim Byrnes,Natsuko Ishida,Andreas Löffler,Sven Höfling,Tetsuo Ogawa,Alfred Forchel,Yoshihisa Yamamoto +11 more
TL;DR: In this article, a new lasing showing a unique spectrum based on a highly excited exciton-polariton condensate was implemented, which matched a theory describing nonequilibrium system.
Proceedings ArticleDOI
Two-photon interference from the resonance fluorescence of a single quantum dot in a microcavity
TL;DR: In this article, the Fourier transform-limited two-photon interference of two singlephoton pulses on a beam-splitter is considered and the critical ingredient to create ideal photons is the process of initial excitation of the emitter which strongly influences the coherence properties of the photons.
Proceedings ArticleDOI
Photon emission statistics and coherence properties of high-ß semiconductor microcavity lasers
S. M. Ulrich,Christopher Gies,Serkan Ates,Jan Wiersig,Stephan Reitzenstein,C. Hofmann,Andreas Löffler,Alfred Forchel,Frank Jahnke,Peter Michler +9 more
TL;DR: In this article, first-and second-order correlation experiments on high-s micropillar lasers are presented, which trace a smooth transition from spontaneous to stimulated emission, based on refined theoretical calculations on semiconductor microlaser emission characteristics.
Journal ArticleDOI
Magneto-optical cavity quantum electrodynamics effects in quantum dot - micropillar systems
Stephan Reitzenstein,S. Munch,P. Gold,P. Franeck,A. Rahimi-Iman,Andreas Löffler,Sven Höfling,L. Worschech,Ilya Ponomarev,T. L. Reinecke,Alfred Forchel +10 more
TL;DR: In this article, the magnetic field employed in Faraday configuration induces a transition from strong coupling towards the critical coupling regime which is explained in terms of a magnetic field dependent oscillator strength of the In0.3Ga0.7As QDs.
Proceedings ArticleDOI
Electrically driven quantum dot high quality factor micropillar cavities
Sven Höfling,Stephan Reitzenstein,C. Böckler,C. Kistner,R. Debusmann,Andreas Löffler,Alfred Forchel,Julien Claudon,Laurent Grenouillet,Jean-Michel Gérard +9 more
TL;DR: In this paper, an electrically driven quantum dot micropillar cavities with quality factors up to 16.000 were reported, which allowed the observation of pronounced single dot resonance effects with a Purcell enhancement.
