TL;DR: A design principle is proposed to realize achromatic metasurface devices which successfully eliminate the chromatic aberration over a continuous wavelength region from 1200 to 1680 nm for circularly-polarized incidences in a reflection scheme.

TL;DR: A metalens array made of gallium nitride (GaN) nanoantennas that can be used to capture light-field information and demonstrate a full-colour light- field camera devoid of chromatic aberration is described.

TL;DR: The versatility and compactness of the MPG capable of transforming any incident wave into light beams of arbitrary polarizations over a broad spectral range are an important step forward in achieving a complete set of flat optics for integrated photonics with far-reaching applications.

TL;DR: The approach with low-cost, semiconductor fabrication compatibility and high working efficiency characteristics offers a way for establishing a complete set of flat optical components for a wide range of applications such as compact imaging sensors, optical spectroscopy, and high-resolution lithography, just named a few.

TL;DR: In this article, an on-chip polarimetry based on the visible metasurfaces for addressing the issue of polarization analysis with compact components is presented, which can effectively determine a set of Stokes parameters covering a broad wave-band at visible light.
