Claims20
A metalens with a hybrid surface topology including a collection of nanopillars and a collection of nanogratings.
A method of metalens topology optimization, wherein the method uses a processor coupled with stored instructions implementing the method, wherein the instructions, when executed by the processor carry out at least some steps of the method, comprising:
- initializing a topology of a metalens using a collection of nanopillars arranged on a substrate;
- and
- optimizing the collection of the nanopillars to produce a hybrid topology for nanostructures of the metalens including nanopillars and nanogratings.
A method for manufacturing a metalens, comprising:
- collecting a hybrid surface topology of a metalens including a collection of nanopillars and a collection of nanogratings;
- and
- manufacturing the metalens having the hybrid surface topology.
