Journal ArticleDOI
Fabrication of dense diameter-tuned quantum dot micropillar arrays for applications in photonic information processing
TL;DR: In this article, a large-scale array of 900 quantum dot micropillar cavities with high spectral homogeneity was realized for photonic information processing such as optical reservoir computing which can be implemented in large arrays of optically coupled microlasers.
Journal ArticleDOI
Generating single photons at GHz modulation-speed using electrically controlled quantum dot microlenses
Alexander Schlehahn,Ronny Schmidt,C. Hopfmann,J.-H. Schulze,André Strittmatter,Tobias Heindel,Liron Gantz,E. R. Schmidgall,David Gershoni,Stephan Reitzenstein +9 more
TL;DR: In this paper, the authors reported the generation of single-photon pulse trains at a repetition rate of up to 1 GHz by modulating the external voltage applied on an electrically contacted quantum dot microlens, which is optically excited by a continuous-wave laser.
Journal ArticleDOI
Room temperature operation of an in-plane half-adder based on ballistic Y-junctions
TL;DR: In this article, an in-plane half-adder (HA) structure based on monolithically interconnected GaAs-AlGaAs Y-branched nanojunctions was realized.
Journal ArticleDOI
High beta lasing in micropillar cavities with adiabatic layer design
M. Lermer,Niels Gregersen,Michael Lorke,E. Schild,P. Gold,Jesper Mørk,Christian Schneider,Alfred Forchel,Stephan Reitzenstein,Sven Höfling,Martin Kamp +10 more
TL;DR: In this article, a detailed study of the threshold pump power and the spontaneous emission β factor in the lasing regime for different diameters dc is presented, demonstrating a reduction in power by over 2 orders of magnitude from dc 2.25 µm down to 0.95 µm.
Journal ArticleDOI
Strong light-matter coupling in the presence of lasing
Christopher Gies,F. Gericke,Paul Gartner,Steffen Holzinger,C. Hopfmann,Tobias Heindel,Janik Wolters,C. Schneider,Matthias Florian,Frank Jahnke,Sven Höfling,Sven Höfling,Martin Kamp,Stephan Reitzenstein +13 more
TL;DR: In this article, the authors provide a generalized criterion for strong coupling and the corresponding emission spectrum, which includes the influence of higher Jaynes-Cummings states, and demonstrate that strong coupling may persevere even at elevated excitation levels sufficient to cross the threshold to lasing.
