Abstract

Spectral filtering device including a dielectric substrate, a first filter capable of acting as a passband filter in the visible range and having a plurality of first nanostructures with a uniform spacing between each other. Each nanostructure has a portion of dielectric material arranged between two portions of metallic material such that one of the two portions of metallic material is arranged between the substrate and the portion of dielectric material. A second filter capable of acting as a passband filter in the infrared range is also included having a plurality of second nanostructures with a uniform spacing between each other and each comprising a portion of dielectric material of which only one face is in contact with a portion of metallic material.
