Structured light with inhomogeneous phase, amplitude, and polarization spatial distributions
that represent an infinite-dimensional space of eigenstates for light as the ideal carrier can …

Scientists have known for more than a century that light possesses both linear and angular
momenta along the direction of propagation. However, only recent advances in optics have …

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 …

We generate tightly focused optical vector beams whose electric fields spin around an axis
transverse to the beams' propagation direction. We experimentally investigate these fields …

Unlike the conventional spin Hall effect of light (SHEL) originating from the light-matter
interaction, the spin-dependent splitting in the geometric SHEL is purely a geometric effect …

The photonic spin Hall effect (PSHE), as an exotic analogy to the spin Hall effect in
electronics, is induced by the spin-orbit interaction of light and manifests itself as a spin …

Lateral momentum conservation is typically kept in a non-absorptive rotationally symmetric
system through mirror symmetry via Noether's theorem when illuminated by a homogeneous …

Vector beams, beams with a non-uniform state of polarization, have become an
indispensable tool in many areas of science and technology. Harnessing topological light …

The spin-orbit interaction of light has been extensively examined in reflection and refraction
at diverse optical interfaces, which results in the discovery of photonic spin Hall effect (SHE) …

Focusing of a vectorial (electromagnetic) optical beam through a high numerical aperture
can be investigated by means of the Richards–Wolf diffraction integral. However, such an …
