Abstract
Provided is an optical detector that includes a photoelectric conversion layer in which photoelectric conversion elements are in a matrix shape and a filter layer including complementary color filters on an incident surface of the photoelectric conversion layer, where each of the complementary color filters blocks a specific wavelength in the incident light. The optical detector further includes a metasurface layer including metasurface elements between the photoelectric conversion layer and the filter layer, where each of the metasurface elements is associated with a corresponding set of photoelectric conversion elements of the photoelectric conversion elements, and each of the metasurface elements includes refractive index materials. Each of the metasurface elements separates, by wavelengths, light having passed through the complementary color filters, into components through the refractive index materials, and guides the components of the light separated by wavelengths toward the corresponding set of photoelectric conversion elements.
