Abstract: The present disclosure provides meta-optical elements and image sensors using a meta-pattern and apparatuses including the image sensors. In an embodiment, an image sensor includes a plurality of pixels. Each pixel of the plurality of pixels includes a photoelectric conversion layer including at least one photoelectric conversion element, and a color routing meta-structure layer provided at a position facing the photoelectric conversion layer. The color routing meta-structure layer includes a meta-structure having a symmetrical structure with respect to a center of a corresponding pixel, and a multi-layer structure having a refractive index that varies in a direction perpendicular to a light-incident surface.

Abstract: An image sensor is provided for obtaining an ultra-high resolution image. The image sensor includes a plurality of two-dimensionally arranged pixels, each of the plurality of pixels including a first meta-photodiode that selectively absorbs light of a red wavelength band, a second meta-photodiode that selectively absorbs light in a green wavelength band, and a third meta-photodiode that selectively absorbs light of a blue wavelength band. A width of each of the plurality of pixels of the image sensor may be less than a diffraction limit.
