The present invention relates to a meta lens, a method for manufacturing the same, and an optical device including the same. According to an aspect of the invention, the substrate; And a dielectric layer forming a geometric metasurface on the substrate, the substrate including a plurality of continuous unit cells, the dielectric layer including a plurality of nanostructures, and one unit One nanostructure is disposed in the cell, and a beam incident through a light source is transmitted to the nanostructure to control phase, so that the transmitted beam has an orbital angular momentum and is focused on a predetermined focal length. Can be. |
