Geometric phase is a unifying and central concept in physics, including optics. As a matter of
fact, optics played a pivotal role from the inception of this new paradigm, as some of the first …

Computing metasurfaces are two-dimensional artificial nanostructures capable of
performing mathematical operations on the input electromagnetic field, including its …

Perfect vortex beams are the orbital angular momentum (OAM)-carrying beams with fixed
annular intensities, which provide a better source of OAM than traditional Laguerre …

The photonic spin Hall effect (SHE) originates from the interplay between the photon-spin
(polarization) and the trajectory (extrinsic orbital angular momentum) of light, ie the spin-orbit …

In this Letter, a new, to the best of our knowledge, type of autofocusing and symmetric beam
arisen from two quartic spectral phases is introduced in theory and experiment. The …

We propose a novel approach to designing an ultrathin polarization-independent metalens
(PIM) by utilizing antennas without rotational invariance. Two arrays of nanoblocks are …

We demonstrate a novel polarization-resolved device (PRD) with the ability to accurately
resolve the polarization states via a simple measurement process. The PRD is composed of …
