Abstract

We propose a novel concept for refractive-index optical sensing with enhanced sensitivity and robustness to source intensity. The design is based on dielectric Huygens’ metagratings and shows 26 times higher sensitivity than conventional blazed gratings. © 2020 The Author(s) OCIS codes: (280.4788) Optical sensing and sensors; (350.4238) Nanophotonics and photonic crystals.
