Propagation loss in photonic crystal waveguides embedding InAs/GaAs quantum dots determined by direct spectral imaging
Lorenzo Scarpelli,Ben Lang,Francesco Masia,Daryll Beggs,Egor A. Muljarov,Andrew B Young,Ruth Oulton,Sven Höfling,Christian Schneider,Wolfgang Werner Langbein +9 more
TL;DR: In this paper, the propagation loss of GaAs photonic crystal waveguides by spectral imaging of the spontaneous emission from the embedded InAs/GaAs quantum dots was determined, compared with the loss obtained by imaging the near field of the out-ofplane radiation of the waveguide mode propagating within the light cone.
Proceedings ArticleDOI
Photon-number-resolving detectors integrated in GaAs waveguide
Alessandro Gaggero,Francesco Mattioli,Roberto Leoni,Dondu Sahin,Zili Zhou,S. Jahanmirinejad,Andrea Fiore,J. Beez,M. Lermer,M. Kamp,Sven Höfling +10 more
TL;DR: In this article, a waveguide photon number resolving detector (WPNR) is proposed to discriminate between 0-4 photons using a spatially multiplexed array of superconducting nanowire single photon detectors.
Proceedings ArticleDOI
Exciton-polariton laser diodes
Christian Schneider,Na Young Kim,A. Rahimi-Iman,Wolfgang Hartmut Nitsche,M. Lermer,Martin Kamp,Stephan Reitzenstein,L. Worschech,Sven Höfling,Yoshihisa Yamamoto,Alfred Forchel +10 more
TL;DR: In this article, four InGaAs quantum wells were integrated in high quality factor doped distributed Bragg reflector microcavities to preserve the strong coupling regime between excitons and photons across the threshold of polariton lasing.
Journal ArticleDOI
Oscillations of the Degree of Circular Polarization in the Optical Spin Hall Effect
D. Schmidt,Bernd Berger,Manfred Bayer,Manfred Bayer,C. Schneider,Sven Höfling,Evgeny Sedov,Alexey Kavokin,Alexey Kavokin,Marc Aßmann +9 more
TL;DR: In this paper, a detailed analysis of momentum space dynamics of the exciton polariton pseudospin is presented, and the authors attribute the higher modulation to additional components of the effective magnetic field which have been neglected in the foundational theory of the optical spin Hall effect.
Proceedings ArticleDOI
A broadband micropillar cavity device for high extraction efficiency of photon pairs
Laia Gines,Magdalena Moczała-Dusanowska,David Dlaka,Radim Hošák,Junior R. Gonzales-Ureta,Miroslav Ježek,Edmund Harbord,Ruth Oulton,Sven Höfling,Andrew J. Young,O. Schneider,Ana Predojević +11 more
TL;DR: In this article , the authors present a novel device capable of enhanced and broadband collection of pairs of photons emitted by a single semiconductor quantum dot, which can be viewed as a quantum antenna.
