Polarization-insensitive beam splitters using all-dielectric phase gradient metasurfaces at visible wavelengths. Optics letters, 43(18), 4350-4353. | Abstract: | Beam splitters play important roles in several optical applications, such as interferometers, spectroscopy, and optical communications. In this study, we propose and numerically examine polarization-insensitive beam splitters utilizing two-step phase gradient all-dielectric metasurfaces in the visible spectrum. The metasurface is made of periodically arranged binary unit cells, and phase difference between neighboring unit cells on the surface is 180 deg. The metasurface is shown to have a special phase gradient whose sign changes periodically. The angle of the split beams on both sides and the corresponding total transmission value at 532 nm wavelength are found to be 46.8° and 0.90, respectively. | URI: | https://doi.org/10.1364/OL.43.004350 https://hdl.handle.net/20.500.11851/769 |
