The growing maturity of nanofabrication has ushered massive sophisticated optical
structures available on a photonic chip. The integration of subwavelength-structured …

The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

Optical vortices, beams with spiral wavefronts and screw phase dislocations, have been
attracting increasing interest in various fields. Here, we theoretically propose and …

Metasurfaces are ultrathin metamaterials consisting of planar electromagnetic (EM)
microstructures (eg, meta-atoms) with pre-determined EM responses arranged in specific …

In the wake of intense research on metamaterials the two-dimensional analogue, known as
metasurfaces, has attracted progressively increasing attention in recent years due to the …

Surfaces covered by ultrathin plasmonic structures—so-called metasurfaces,,,—have
recently been shown to be capable of completely controlling the phase of light, representing …

Metasurfaces are planar metamaterials exhibiting certain inhomogeneous phase
distributions for transmitted or reflected waves, which can efficiently reshape the wave‐fronts …

The spin Hall effect of light refers to a spin-dependent transverse splitting of light at a planar
interface. Previous demonstrations to enhance the splitting have suffered from exceedingly …

The spin Hall effect (SHE) of light, as an analogue of the SHE in electronic systems, is a
promising candidate for investigating the SHE in semiconductor spintronics/valleytronics …
