Abstract: A combination structure includes a hybrid nanostructure array and a light-absorbing layer adjacent to the hybrid nanostructure array. The hybrid nanostructure array includes a plurality of hybrid nanostructures, each hybrid nanostructure includes a stack of a first nanostructure and a second nanostructure. The first nanostructure includes a first material. The second nanostructure includes a second material. The second material has a refractive index that is higher than a refractive index of the first material. The light-absorbing layer includes a near-infrared absorbing material configured to absorb light of at least a portion of a near-infrared wavelength spectrum.

Abstract: A combination structure includes an in-plane pattern of unit cells, wherein the each unit cell includes nanostructures each having a dimension that is smaller than a near-infrared wavelength and a light-absorbing layer adjacent to the nanostructures and including a near-infrared absorbing material configured to absorb light in at least a portion of a near-infrared wavelength spectrum. The nanostructures are define a nanostructure array in the unit cells, and a wavelength width at 50% transmittance of a transmission spectrum in the near-infrared wavelength spectrum of the combination structure is wider than a wavelength width at 50% transmittance of a transmission spectrum in the near-infrared wavelength spectrum of the nanostructure array.

Abstract: An optical filter includes a near-infrared absorbing layer including a first material, the first material being configured to absorb light in a first wavelength spectrum belonging to a near-infrared wavelength spectrum. The optical filter includes a compensation layer adjacent to the near-infrared absorbing layer, the compensation layer including a second material different from the first material. The optical filter includes a metamaterial structure spaced apart from the near-infrared absorbing layer via the compensation layer, the metamaterial structure being configured to absorb or reflect light in a second wavelength spectrum at least partially overlapped with the first wavelength spectrum.
