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…
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.…
