Meta-optical element and method of producing meta-optical element

Abstract

The super-optical element of the present invention comprises: a support substrate having a first surface and having a plurality of openings formed by sidewalls and bottom walls disposed on the side of the first surface; and a pattern layer comprising a plurality of embedded members, the plurality of embedded members being formed by filling the openings with a component having a higher refractive index than the component constituting the sidewalls; and the depth C of the openings being 1.0 μm or more, the distance A being defined as the shortest distance between the centroid GA of the cross section at a position 0.1C from the first surface and the shortest distance between the centroid GB of the cross section at a position 0.9C from the first surface and the shortest distance between the centroid GB and the shortest distance between the cross section, the aspect ratio expressed as "C / ((A+B) / 2)" being 3.0 or more, and the angle Φ formed by the line passing through the centroid GA and the centroid GB and the line orthogonal to the first surface being 0.0 to 10.0°.
