Journal ArticleDOI
Optical Spin Hall Effect
TL;DR: A remarkable analogy is established between the well-known spin Hall effect and the polarization dependence of Rayleigh scattering of light in microcavities and spin polarizations of the polaritons scattered clockwise and anticlockwise have different signs.
Journal ArticleDOI
Observation of Half-Quantum Vortices in an Exciton-Polariton Condensate
Konstantinos G. Lagoudakis,Tomas Ostatnický,Alexey Kavokin,Alexey Kavokin,Yuri G. Rubo,Régis André,Benoit Deveaud-Plédran +6 more
TL;DR: Two-dimensional superfluids carrying spin are expected to demonstrate a different type of elementary excitations referred to as half-quantum vortices, characterized by a ρ rotation of the phase and a π rotation ofThe polarization vector when circumventing the vortex core.
Journal ArticleDOI
Observation of the optical spin Hall effect
C. Leyder,M. Romanelli,J. Ph. Karr,Elisabeth Giacobino,Timothy Chi Hin Liew,Mikhail M. Glazov,Alexey Kavokin,Guillaume Malpuech,Alberto Bramati +8 more
TL;DR: In this article, the optical spin Hall effect was observed in a high-quality GaAs/AlGaAs quantum microcavity, where the spin current was controlled by the linear polarization of the laser pump.
Journal ArticleDOI
Exciton–polariton spin switches
Alberto Amo,Timothy Chi Hin Liew,C. Adrados,Romuald Houdré,Elisabeth Giacobino,Alexey Kavokin,Alberto Bramati +6 more
TL;DR: In this paper, an all-optical spin switch based on exciton-polaritons in a semiconductor microcavity is demonstrated, which may lead to small and fast spin-based on-chip logic devices.
Journal ArticleDOI
Lossless interface modes at the boundary between two periodic dielectric structures
TL;DR: In this paper, it was shown that Tamm states of light can be formed at the boundary between two periodical dielectric structures, one having a period close to the wavelength of light and another having a time complexity close to double of the wavelength.
