More Information
Summary:Provided is an optical device including a dielectric transparent substrate and a metallic layer having a thickness between about 20 nm and about 1000 nm disposed on the transparent substrate. The metallic layer comprises at least one localized group of cavities, each localized group being confined within a diameter smaller than about 5 um, and each localized group comprising at least two cavities, with a distance between two adjacent cavities in the localized group being between about 100 nm and about 2000 nm. Each cavity in the localized group is shaped as a through-hole in the metallic layer, the through hole having a polygonal cross-section having a polygon side length between 50 nm and 2000 nm.
