Journal ArticleDOI
Inverse design and demonstration of a compact and broadband on-chip wavelength demultiplexer
Alexander Y. Piggott,Jesse Lu,Konstantinos G. Lagoudakis,Jan Petykiewicz,Thomas M. Babinec,Jelena Vuckovic +5 more
TL;DR: An on-chip integrated wavelength demultiplexer designed using an inverse computational algorithm is experimentally demonstrated in this paper, where 1,300 and 1,550 nm wavelength light is sorted in a device area of just 2.8 µm2.
Journal ArticleDOI
Quantized vortices in an exciton–polariton condensate
Konstantinos G. Lagoudakis,Michiel Wouters,Michiel Wouters,Maxime Richard,A. Baas,Iacopo Carusotto,Régis André,D. Le Si Dang,Benoit Deveaud-Plédran +8 more
TL;DR: In this paper, the spontaneous formation of pinned quantized vortices in the Bose-condensed phase of a polariton fluid was observed in a solid state system made of exciton polaritons.
Journal ArticleDOI
Superconducting nanowire photon-number-resolving detector at telecommunication wavelengths
Alexander Divochiy,Francesco Marsili,David Bitauld,Alessandro Gaggero,Roberto Leoni,Francesco Mattioli,Alexander Korneev,Vitaliy Seleznev,Nataliya Kaurova,Olga Minaeva,Gregory Goltsman,Konstantinos G. Lagoudakis,Moushab Benkhaoul,Francis Lévy,Andrea Fiore,Andrea Fiore +15 more
TL;DR: The drive to develop detectors capable of counting the number of photons in a weak optical pulse is motivated by potential applications in quantum computing as discussed by the authors, where superconducting nanostructures are one exciting approach: offering high sensitivity and operate at repetition rates up to 80 MHz.
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
Coherent oscillations in an exciton-polariton Josephson junction.
Konstantinos G. Lagoudakis,Barbara Piętka,Michiel Wouters,Régis André,Benoit Deveaud-Plédran +4 more
TL;DR: The time resolved population and phase dynamics reveal the analogy with the ac Josephson effect, and a theoretical two-mode model describes the observed effects, explaining how the different realizations of the pulsed experiment can be in phase.
