ALEXANDRIA, Va., Sept. 17 -- United States Patent no. 12,416,752, issued on Sept. 16, was assigned to PRESIDENT AND FELLOWS OF HARVARD COLLEGE (Cambridge, Mass.).
"Polarization state generation with a metasurface" was invented by Noah A. Rubin (Cambridge, Mass.) and Federico Capasso (Cambridge, Mass.).
According to the abstract* released by the U.S. Patent & Trademark Office: "The present disclosure provides an optical component, which may be a metasurface grating, including (a) a substrate; and (b) an array of subwavelength-spaced phase-shifting elements, which are tessellated on the substrate to produce, when illuminated with a polarized incident light, a diffracted light beam with a distinct polarization state for each of a finite numb...
