All-dielectric refractive index sensor based on Fano resonance with high sensitivity in the mid-infrared region

We design and numerically analyze a Fano resonance device based on periodical all-dielectric “lucky knot” shaped nanostructure in the mid-infrared region with high sensitivity, which is insensitive to polarization and incident angle. The proposed nanostructure is sensitive to the change of the refra...
