Abstract

See full text

Polarization-insensitive metasurfaces using anisotropic nanostructures are disclosed. These anisotropic structures allow for an accurate implementation of phase, group delay, and group delay dispersion, while simultaneously making it possible to realize a polarizationinsensitive, diffraction-limited and achromatic metalens for wavelength, e.g., λ=from about 460 nm to about 700 nm. The approach of polarization-insensitivity can be also applied for other metasurface devices with applications in, e.g., imaging and virtual or augmented reality.
