Polarized upconversion emission at metasurface

Light Sci Appl. 2023 Nov 6;12(1):263. doi: 10.1038/s41377-023-01301-4.

Abstract

Leveraging the resonant modes of all-dielectric metasurfaces, specifically quasi-bound state in the continuum and Mie resonances, the precise orthogonal polarization control has been realized.
