Room temperature valley coherence in monolayer WSe2 mediated by chiral nematic liquid crystal
Hassan Lamsaadi, Andrea Balocchi, Aurélien Cuche +5
Valley coherence refers to a phase-coherent superposition of inequivalent momentum valleys, in which quantum information can be encoded in the relative valley phase. Chiral nematic…
Emergence of Localized Surface Plasmons in Unpatterned Hyperdoped Polycrystalline Silicon
Mohamad Bahsoun, Jesse Groenen, Gonzague Agez +7
The ability to engineer localized surface plasmon resonances at large scale usually relies on precise nanoscale patterning. Here, we demonstrate that mid-infrared plasmonic respons…
Directional silicon nano-antennas for quantum emitter control designed by evolutionary optimization
Romain Hernandez, Peter R. Wiecha, Jean-Marie Poumirol +5
We optimize silicon nano-antennas to enhance and steer the emission of local quantum sources. We combine global evolutionary optimization (EO) with frequency domain electrodynamica…
Control of light emission of quantum emitters coupled to silicon nanoantenna using cylindrical vector beams
Martin Montagnac, Yoann Brûlé, Aurélien Cuche +11
Light emission of europium (Eu3+) ions placed in the vicinity of optically resonant nanoantennas is usually controlled by tailoring the local density of photon states (LDOS). We sh…
Probing the optical near-field interaction of Mie nanoresonators with atomically thin semiconductors
Ana Estrada-Real, Ioannis Paradisanos, Peter R. Wiecha +10
Optical Mie resonators based on silicon nanostructures allow tuning of light-matter-interaction with advanced design concepts based on CMOS compatible nanofabrication. Optically ac…
Engineered Near and Far Field Optical Response of Dielectric Nanostuctures using Focused Cylindrical Vector Beams
Martin Montagnac, Gonzague Agez, Adelin Patoux +2
Near- and far-field optical properties of silicon nanostructures under linear polarization (Gaussian beam), and azimuthally or radially focused cylindrical vector beams are investi…
Unveiling the optical emission channels of monolayer semiconductors coupled to silicon nanoantennas
Jean-Marie Poumirol, Ioannis Paradisanos, Shivangi Shree +13
Monolayers (MLs) of transition metal dichalcogenides (TMDs) such as WSe2 and MoSe2 can be placed by dry stamping directly on broadband dielectric resonators, which have the ability…
Ultra-broadband gradient-pitch Bragg-Berry mirrors
Mushegh Rafayelyan, Gonzague Agez, Etienne Brasselet
The realization of geometric phase optical device operating over a broad spectral range is usually confronted with intrinsic limitations depending of the physical process at play.…
Universal shape law of stochastic supercritical bifurcations: Theory and experiments
Gonzague Agez, Marcel G. Clerc, Eric Louvergneaux
A universal law for the supercritical bifurcation shape of transverse one-dimensional (1D) systems in presence of additive noise is given. The stochastic Langevin equation of such…
