Ultrasensitive Refractive Index Sensing Based on the Quasi‐Bound States in the Continuum of All‐Dielectric Metasurfaces (Advanced Optical Materials 19/2022)
Source abstract
Abstract
In article number 2200812, Hui-Hsin Hsiao and co-workers demonstrate a narrowband and ultrahigh sensitivity refractive-index sensor based on all-dielectric metasurfaces. A quasi-bound state in the continuum (quasi-BIC) is excited in tilted silicon nanobar pairs with a dominant toroidal dipole (TD) and electric quadrupole (EQ) resonant feature. For high aspect-ratio nanopillars, the quasi-BIC TD-EQ mode exhibits an enhanced refractive-index sensitivity.
