Towards an experimental proof of superhydrophobicity enhanced by quantum fluctuations freezing on a broadband-absorber metamaterial
M. Sarrazin, I. Septembre, A. Hendrickx +9
Previous theoretical works suggested that superhydrophobicity could be enhanced through partial inhibition of the quantum vacuum modes at the surface of a broadband-absorber metama…
Directing random lasing emission using cavity exciton-polaritons
Paul Bouteyre, Hai Son Nguyen, Jean-Sébastien Lauret +9
Random lasing is an intriguing phenomenon occurring in disordered structures with optical gain. In such lasers, the scattering of light provides the necessary feedback for lasing a…
Tailoring dispersion of room temperature exciton-polaritons with perovskite-based subwavelength metasurfaces
Nguyen Ha My Dang, Dario Gerace, Emmanuel Drouard +6
Exciton-polaritons, elementary excitations arising from the strong coupling regime between photons and excitons in insulators or semiconductors, represent a promising platform for…
Room temperature cavity polaritons with 3D hybrid perovskite - Towards low-cost polaritonic devices
Paul Bouteyre, Hai Son Nguyen, Jean-Sébastien Lauret +9
Hybrid halide perovskites are now considered as low-cost materials for contemporary research in photovoltaics and nanophotonics. In particular, because these materials can be solut…
Absorption enhancement in amorphous silicon photonic crystals for thin film photovoltaic solar cells
Ounsi El Daif, Emmanuel Drouard, Yeonsang Park +8
We report on very high enhancement of thin layer's absorption through band-engineering of a photonic crystal structure. We realized amorphous silicon (aSi) photonic crystals, where…
