Metasurfaces constituted of a continuously-tuned lattice of coupled nanopillars: inter-coupled metasurfaces

  title={Metasurfaces constituted of a continuously-tuned lattice of coupled nanopillars: inter-coupled metasurfaces},
  author={Huseyin Bilge Yaugci and Hilmi Volkan Demir},
  journal={arXiv: Optics},
Metasurfaces are subwavelength-thick constructs, consisting of discrete meta-cells providing discretized levels of phase accumulation that collectively approximate a designed optical functionality. The meta-cells utilizing Pancharatnam-Berry phase with polarization-converting structures produced encouraging implementations of optical components including metasurface lenses (metalenses). However, a pending and fundamental problem of this approach is the low device efficiency that the resulting…

A broadband achromatic polarization-insensitive metalens consisting of anisotropic nanostructures

A polarization-insensitive metalens is demonstrated using otherwise anisotropic nanofins which offer additional control over the dispersion and phase of the output light, allowing achromatic and polarization- insensitive behaviour across the entire visible spectrum.

Multiwavelength metasurfaces through spatial multiplexing

It is shown that spatial multiplexing schemes can be applied to increase the number of operation wavelengths and an important feature of this method is its simple generalization to adding more wavelengths or new functionalities to a device.
