Abstract
This disclosure provides various examples and methods of manufacturing metasurface couplers, including slanted grating metasurface couplers characterized by a plurality of parallel, elongated angled ridges. In some examples, a transmission-mode metasurface coupler with a slanted grating is used to couple optical radiation into a waveguide. In some examples, a reflection-mode metasurface coupler with a slanted grating and reflective layer is used to couple optical radiation into a waveguide.
