TL;DR: The results firmly establish that metalenses can have widespread applications in laser-based microscopy, imaging, and spectroscopy, with image qualities comparable to a state-of-the-art commercial objective.

TL;DR: In this paper, a classification of metasurfaces based on their different phase mechanisms and profiles and a comparison between plasmonic and dielectric surfaces is presented. And the authors place particular emphasis on the recent developments on electric and magnetic field control of light with Dielectric nanostructures and highlight the physical mechanisms and designs required for efficient all-dielectric metamaterials.

TL;DR: This work presents a method allowing for the imposition of two independent and arbitrary phase profiles on any pair of orthogonal states of polarization-linear, circular, or elliptical-relying only on simple, linearly birefringent wave plate elements arranged into metasurfaces.

TL;DR: A metasurface converter for optical states that transforms polarization states into optical angular momentum states and illustrates a general material-mediated connection between SAM and OAM of light and may find applications in producing complex structured light and in optical communication.

TL;DR: These metalenses are less than 600 nm-thick and can focus incident light down to diffraction-limited spots as small as ∼0.64λ and provide high-resolution imaging, which makes them highly promising for widespread applications in imaging and spectroscopy.
