Abstract

An optical device includes a transparent substrate and a conductive layer disposed over an upper surface of the transparent substrate. The conductive layer defines at least one groove inwardly extending from an upper surface and includes an aperture that is spaced apart from the at least one groove. An interface between the upper surface of the conductive layer and an ambient medium defines an optical branch along which surface plasmon polariton modes are excited in response to at least partially coherent light being received by the optical device.
