Patent 11604364 was granted and assigned to President and Fellows of Harvard College on March, 2023 by the United States Patent and Trademark Office.
An optical component comprises a metasurface comprising nanoscale elements. The metasurface is configured to receive incident light and to generate optical outputs. The geometries and/or orientations of the nanoscale elements provide a first optical output upon receiving a polarized incident light with a first polarization, and provide a second optical output upon receiving a polarized incident light with a second polarization that is different from the first polarization.
