Metalenses Based on Symmetric Slab Waveguide and c-TiO(2): Efficient Polarization-Insensitive Focusing at Visible Wavelengths
A key goal of metalens research is to achieve wavefront shaping of light using optical elements with thicknesses on the order of the wavelength. Here we demonstrate ultrathin highly efficient crystalline titanium dioxide metalenses at blue, green, and red wavelengths (λ(0) = 453 nm, 532 nm, and 633...
