Abstract: An image sensor includes a sensor substrate including a plurality of pixels for sensing incident light, and a nano-photonic microlens array arranged to face a light incident surface of the sensor substrate, and including a plurality of nano-photonic microlenses for condensing incident light. Each of the plurality of pixels includes a plurality of photosensitive cells that are two-dimensionally arranged in a first direction and a second direction perpendicular to the first direction and are configured to independently sense the incident light, and an isolation for electrically isolating the plurality of photosensitive cells, each of the nano-photonic microlenses includes a plurality of nano-structures that are arranged such that the light transmitting each of the nano-photonic microlenses has a convex phase profile, and the plurality of nano-structures are arranged in the form of a two-dimensional array in a diagonal direction between the first direction and the second direction.

Abstract: Provided is an image sensor including a metasurface having a light resonance function. The image sensor includes a photoelectric conversion layer, an interlayer material layer on the photoelectric conversion layer, and a single meta pattern layer on the interlayer material layer, wherein the meta pattern layer includes a metasurface, the metasurface having a same phase profile as that of a lens, and the meta pattern layer has a height that causes a resonance at a given wavelength of incident light to block transmission of the given wavelength through the meta pattern layer.
