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…

Enhanced Delayed Fluorescence in Non-Local Metasurfaces: The Role of Electronic Strong Coupling
Yu-Chen Wei, Chih-Hsing Wang, Konstantinos S. Daskalakis +3
Strong light-matter coupling has garnered significant attention for its potential to optimize optoelectronic responses. In this study, we designed open cavities featuring non-local…
