Abstract
A metasurface device includes a dielectric layer, an aluminum nanodisk and an aluminum layer. The dielectric layer includes top and bottom surfaces that are opposite each other. The dielectric layer also includes at least one ring-like cavity that extends between the top and bottom surfaces of the dielectric layer. The aluminum nanodisk is formed in the at least one ring-like cavity in the dielectric layer. The aluminum layer is formed on the dielectric layer and includes at least one ring-like cavity that extends between top and bottom surfaces of the aluminum layer. Each ring-like cavity in the aluminum layer corresponds to a ring-like cavity in the dielectric layer. Two or more analytes may emit fluorescence in response to light of a predetermined wavelength being incident on the metasurface device and in which the two or more analytes are present at the dielectric layer.
