Bound States in the Continuum Empower Subwavelength Gratings for Refractometers in Visible

This paper describes a compact refractometer in visible with optical bounds states in the continuum (BICs) using silicon nitride (Si<sub>3</sub>N<sub>4</sub>) based sub-wavelength medium contrast gratings (MCGs). The proposed device is highly sensitive to different polarizati...
