Abstract:We investigate the feasibility of a full-silica transmission metasurface exhibiting optical properties equivalent to a quarterwave plate at the wavelength of 351 nm as an alternative to anisotropic crystals. We report the design, manufacturing process and optical characterization of full-silica quarter waveplates. We evidence the possibility to obtain a full-silica component exhibiting at 351 nm a high damage threshold and a phase retardance of /4 associated with a transmission efficiency higher than 95%.
