Abstract
A meta-lens includes a first layer that is arranged on a substrate and that includes a plurality of first nanostructures and a second layer including a plurality of second nanostructures separately arranged from the first nanostructures. The meta-lens may focus light of a plurality of wavelengths or light of a wide wavelength bandwidth due to the arrangement of the nanostructures in a multilayer structure.
Claims22
A meta-lens comprising:
- a substrate;
- a first layer arranged on the substrate, the first layer comprising a plurality of first nanostructures comprising a material having a refractive index different from a refractive index of the substrate;
- a spacer layer covering the plurality of first nanostructures, the spacer layer comprising a material having a refractive index different from the refractive index of the plurality of first nanostructures;
- and
- a second layer arranged on the spacer layer, the second layer comprising a plurality of second nanostructures comprising a material having a refractive index different from the refractive index of the spacer layer.
