    Abstract: Provided are meta illuminators. The meta illuminators according to embodiments include a first light emitter configured to emit pattern light, and a second light emitter configured to emit non-patterned light, wherein the first and second light emitters forms a single body. The first and second light emitters respectively include meta-surfaces that are different from each other, and the different meta-surfaces may be formed on a single material layer. The first light emitter includes a pattern region that transmits a portion of incident light, and the second light emitter does not include the pattern region. A mask may be arranged between the light source and the transparent substrate.

    Abstract: An image sensor includes a substrate, thin lenses disposed on a first surface of the substrate and configured to concentrate lights incident on the first surface, and light-sensing cells disposed on a second surface of the substrate, the second surface facing the first surface, and the light-sensing cells being configured to sense lights passing through the thin lenses, and generate electrical signals based on the sensed lights. A first thin lens and second thin lens of the thin lenses are configured to concentrate a first light and a second light, respectively, of the incident lights onto the light-sensing cells, the first light having a different wavelength than the second light.

    Abstract: An image sensor includes an optical sensor layer including a plurality of light-sensitive cells configured to sense light to generate electrical signals, and a color filter array layer disposed on the optical sensor layer and including a plurality of color filters respectively facing the plurality of light-sensitive cells. Each of the plurality of color filters includes a nanostructure in which a first material having a first refractive index and a second material having a second refractive index higher than the first refractive index are arranged. The first material and the second material are alternatively positioned at an interval less than a central wavelength of a color of the color filter. Thus, a thin image sensor having good wavelength selectivity and suitable for obtaining high resolution images is provided.
