Abstract
The present disclosure describes anti-reflective structuring of optical elements that include a metasurface. In some implementations, the anti-reflective structuring includes applying one or more anti-reflective coatings over a surface of the metasurface. In some implementations, the anti-reflective structuring includes modifying the shape of the meta-atoms or providing textured features on the meta-atoms so as to reduce reflections.
Claims24
An apparatus comprising:
- an optical element that includes a metasurface;
- and
- a first anti-reflective coating disposed on at least part of the metasurface.
An apparatus comprising:
- an optical element that includes a metasurface,
- wherein the metasurface includes meta-atoms having a shape to reduce optical reflections.
An apparatus comprising:
- an optical element that includes a metasurface, the metasurface including meta-atoms;
- textured anti-reflective features on the meta-atoms.
