Journal ArticleDOI
Observation of non-Hermitian degeneracies in a chaotic exciton-polariton billiard
Tingge Gao,Eliezer Estrecho,Konstantin Y. Bliokh,Timothy Chi Hin Liew,M. D. Fraser,Sebastian Brodbeck,Martin Kamp,Christian Schneider,Sven Höfling,Sven Höfling,Yoshihisa Yamamoto,Franco Nori,Yuri S. Kivshar,Andrew Truscott,Robert Dall,Elena A. Ostrovskaya +15 more
TL;DR: It is demonstrated that non-Hermiticity dramatically modifies the structure of modes and spectral degeneracies in exciton-polariton systems, and, therefore, will affect their quantum transport, localization and dynamical properties.
Journal ArticleDOI
Creation of orbital angular momentum states with chiral polaritonic lenses.
Robert Dall,M. D. Fraser,Anton S. Desyatnikov,Guangyao Li,Sebastian Brodbeck,Martin Kamp,Christian Schneider,Sven Höfling,Sven Höfling,Elena A. Ostrovskaya +9 more
TL;DR: This work demonstrates a simple and efficient approach to the generation of nontrivial orbital angular momentum states by using optically induced potentials-chiral polaritonic lenses.
Journal ArticleDOI
Zero-dimensional polariton laser in a subwavelength grating-based vertical microcavity
Bo Zhang,Zhaorong Wang,Sebastian Brodbeck,Christian Schneider,Martin Kamp,Sven Höfling,Sven Höfling,Hui Deng +7 more
TL;DR: Zhang et al. as discussed by the authors demonstrate full non-destructive confinement of polaritons using a hybrid cavity composed of a single-layer subwavelength grating mirror and a distributed Bragg reflector.
Journal ArticleDOI
Zero Dimensional Polariton Laser in a Sub-Wavelength Grating Based Vertical Microcavity
Bo Zhang,Zhaorong Wang,Sebastian Brodbeck,Christian Schneider,Martin Kamp,Sven Hoefling,Hui Deng +6 more
TL;DR: In this paper, the authors demonstrate full confinement of the polaritons non-destructively using a hybrid cavity made of a single-layer subwavelength grating mirror and a distributed Bragg reflector.
Journal ArticleDOI
Coherent polariton laser
Seonghoon Kim,Bo Zhang,Zhaorong Wang,Julian Fischer,Sebastian Brodbeck,Martin Kamp,Christian Schneider,Sven Höfling,Sven Höfling,Hui Deng +9 more
TL;DR: The emission from a polariton laser shows the coherence that is common to conventional laser, a step toward using them as high-efficiency alternative light sources as mentioned in this paper, which is a promising development.
