Journal ArticleDOI
Exciton-polariton spectra and limiting factors for the room-temperature photoluminescence efficiency in ZnO
Shigefusa F. Chichibu,Akira Uedono,Atsushi Tsukazaki,Takeyoshi Onuma,M. Zamfirescu,Akira Ohtomo,Alexey Kavokin,G. Cantwell,Cole W. Litton,Takayuki Sota,Masashi Kawasaki +10 more
TL;DR: In this article, the static and dynamic responses of excitons in state-of-the-art bulk and epitaxial ZnO epilayers are reviewed to support the possible realization of polariton lasers, which are coherent and monochromatic light sources due to Bose condensation of exciton-polaritons.
Journal ArticleDOI
Cavity-polariton dispersion and polarization splitting in single and coupled semiconductor microcavities
G. Panzarini,Lucio Claudio Andreani,A. Armitage,D. Baxter,M. S. Skolnick,Vasily N. Astratov,J.S. Roberts,Alexey Kavokin,Maria Vladimirova,M. A. Kaliteevski +9 more
TL;DR: In this article, a theoretical and experimental work on linear exciton-light coupling in single and coupled semiconductor microcavities is reviewed: emphasis is given to angular dispersion and polarization effects in the strong coupling regime, where cavity-polariton states are formed.
Journal ArticleDOI
Optical valley Hall effect for highly valley-coherent exciton-polaritons in an atomically thin semiconductor
Nils Lundt,Ł. Dusanowski,Evgeny Sedov,Petr Stepanov,Mikhail M. Glazov,Sebastian Klembt,Martin Klaas,Johannes Beierlein,Ying Qin,Sefaattin Tongay,Maxime Richard,Alexey Kavokin,Sven Höfling,Sven Höfling,Christian Schneider +14 more
TL;DR: In this paper, the authors demonstrate spin and valley-selective propagation of exciton-polaritons in a monolayer of MoSe2 that is strongly coupled to a microcavity photon mode.
Journal ArticleDOI
Chiral Modes at Exceptional Points in Exciton-Polariton Quantum Fluids.
Tingge Gao,Guangyao Li,Eliezer Estrecho,Timothy Chi Hin Liew,D. Comber-Todd,Anton Nalitov,Mark Steger,Kenneth D. West,Loren Pfeiffer,David W. Snoke,Alexey Kavokin,Alexey Kavokin,Alexey Kavokin,Andrew Truscott,Elena A. Ostrovskaya +14 more
TL;DR: The generation of chiral modes-vortex flows with fixed handedness in exciton-polariton quantum fluids is demonstrated and the possibility of exploiting nontrivial and counterintuitive properties of waves near exceptional points in macroscopic quantum systems is demonstrated.
Journal ArticleDOI
Exciton radiative properties in nonpolar homoepitaxial ZnO/(Zn,Mg)O quantum wells
Luc Beaur,Luc Beaur,Thierry Bretagnon,Thierry Bretagnon,Bernard Gil,Bernard Gil,Alexey Kavokin,Alexey Kavokin,Thierry Guillet,Thierry Guillet,Christelle Brimont,Christelle Brimont,Dimitri Tainoff,M. Teisseire,Jean-Michel Chauveau,Jean-Michel Chauveau +15 more
TL;DR: In this article, the exciton lifetime increases linearly with the temperature from a value of 750 ps at 100 K until about 2.4 ns at 325 K, which indicates that radiative recombination of free excitons is dominating the quantum well photoluminescence even at room temperature.
