Journal ArticleDOI
Strong coupling in a single quantum dot–semiconductor microcavity system
Johann Peter Reithmaier,G. Sek,G. Sek,Andreas Löffler,C. Hofmann,S. Kuhn,Stephan Reitzenstein,L. V. Keldysh,V. D. Kulakovskii,T. L. Reinecke,Alfred Forchel +10 more
TL;DR: The observation of strong coupling of a single two-level solid-state system with a photon, as realized by a single quantum dot in a semiconductor microcavity, may provide a basis for future applications in quantum information processing or schemes for coherent control.
Journal ArticleDOI
Photon antibunching from a single quantum-dot-microcavity system in the strong coupling regime.
David Press,S. Gotzinger,Stephan Reitzenstein,Carolin Hofmann,Andreas Löffler,Martin Kamp,Alfred Forchel,Yoshihisa Yamamoto +7 more
TL;DR: This work presents proof that the emission from a strongly-coupled QD- microcavity system is dominated by a single quantum emitter.
Proceedings ArticleDOI
Strong coupling in a single quantum dot semiconductor microcavity system
Stephan Reitzenstein,G. Sek,G. Sek,Andreas Löffler,C. Hofmann,S. Kuhn,Johann Peter Reithmaier,Johann Peter Reithmaier,Leonid Veniaminovich Keldysh,V. D. Kulakovskii,T. L. Reinecke,Alfred Forchel +11 more
TL;DR: In this article, a planar cavity quantum electrodynamics (cQED) system based on a low density In0.3Ga 0.7As quantum layer placed as the active layer in a high quality planar AlAs/GaAs distributed Bragg reflector cavity grown by molecular beam epitaxy is described.
Journal ArticleDOI
AlAs∕GaAs micropillar cavities with quality factors exceeding 150.000
Stephan Reitzenstein,C. Hofmann,A. V. Gorbunov,M. Strauß,Soon-Hong Kwon,Christian Schneider,Andreas Löffler,Sven Höfling,Martin Kamp,Alfred Forchel +9 more
TL;DR: In this paper, the authors report on AlAs∕GaAs micropillar cavities with unprecedented quality factors based on high reflectivity distributed Bragg reflectors (DBRs).
Journal ArticleDOI
Post-selected indistinguishable photons from the resonance fluorescence of a single quantum dot in a microcavity.
TL;DR: A strictly resonant continuous-wave excitation together with controlling the spontaneous emission lifetime of the single quantum dots via tunable emitter-mode coupling (Purcell) is proven as a versatile scheme to generate close to Fourier transform-limited (T2/(2T1)=0.91) single photons even at 80% of the emission saturation level.
