Original Abstract Submitted

Provided is an optical detector in which the sensitivity can be enhanced, occurrence of crosstalk can be suppressed, and good color reproduction property can be attained. The optical detector includes a photoelectric conversion layer in which a plurality of photoelectric conversion elements that generate electric charges by photoelectric conversion based on incident light are formed in a matrix shape, a filter layer including a plurality of complementary color filters that are arranged on an incident surface of the photoelectric conversion layer in a manner corresponding to the plurality of photoelectric conversion elements and that each block a specific wavelength in the incident light, and a metasurface layer including a plurality of metasurface elements that are arranged between the photoelectric conversion layer and the filter layer in a manner corresponding to the plurality of photoelectric conversion elements and that each include a plurality of refractive index materials varying according to wavelengths and having a pitch smaller than a target light wavelength. Each of the plurality of metasurface elements separates, by wavelengths, light having passed through the complementary color filters, into components through the plurality of refractive index materials, and guides the components of the light separated by wavelengths toward the corresponding photoelectric conversion elements.
