We present a theoretical and experimental demonstration of a single layer silicon-based metasurface able to convert any arbitrarily polarized incoming light into linearly polarized light. Our metasurface leverages the topological features of symmetry protected quasi-bound states in the continuum and shows an experimental extinction ratio of ~40dB for two linear cross-polarization excitations, paving the way for a novel class of ultra-compact multi-frequency linear polarizers.

Abstract
We present a theoretical and experimental demonstration of a single layer silicon-based metasurface able to convert any arbitrarily polarized incoming light into linearly polarized light. Our metasurface leverages the topological features of symmetry protected quasi-bound states in the continuum and shows an experimental extinction ratio of ~40dB for two linear cross-polarization excitations, paving the way for a novel class of ultra-compact multi-frequency linear polarizers.File in questo prodotto:
