Far-field radiation of bulk, edge and corner eigenmodes from a finite 2D Su-Schrieffer-Heeger plasmonic lattice
Ãlvaro BuendÃa, José Luis Pura, Vincenzo Giannini +1
Subwavelength arrays of plasmonic nanoparticles allow us to control the behaviour of light at the nanoscale. Here, we develop an eigenmode analysis, employing a coupled electromagn…

Confinement of Polariton Condensates in quasi-Flatband BICs in Plasmonic and Dielectric Metasurfaces
Anton Matthijs Berghuis, Jose Luis Pura, Rafael P. Argante +3
We investigate exciton-polariton condensation in square arrays, composed of either dielectric silicon (Si) or plasmonic silver (Ag) nanodisks, covered with a dye-doped layer. Both…

Robust Circularly Polarized Luminescence via Quasi-Bound States in the Continuum in Intrinsic Chiral Silicon Metasurfaces
Xiao-ke Zhu, Yu-Chen Wei, Jose L. Pura +8
We demonstrate a circularly polarized photoluminescence emission, with dissymmetry factors over 0.1, from achiral organic dye molecules by leveraging quasi-bound st…
