The photonic spin Hall effect (SHE) refers to the transverse spin separation of photons with
opposite spin angular momentum, after the beam passes through an optical interface or …

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 review basic physics and novel types of optical angular momentum. We start with a
theoretical overview of momentum and angular momentum properties of generic optical …

The catenary is the curve that a free-hanging chain assumes under its own weight, and
thought to be a “true mathematical and mechanical form” in architecture by Robert Hooke in …

Controlling the flow of light with nanophotonic waveguides has the potential of transforming
integrated information processing. Because of the strong transverse confinement of the …

The spin Hall effect (SHE) of light is very weak because of the extremely small photon
momentum and spin-orbit interaction. Here, we report a strong photonic SHE resulting in a …

Pancharatnam–Berry (PB) phase has become an effective tool to realize the photonic spin
Hall effect (PSHE) in recent years, due to its capacity of enhancing the spin-orbit interaction …

Light carries both spin and orbital angular momentum. These dynamical properties are
determined by the polarization and spatial degrees of freedom of light. Nano-optics …

We consider reflection and transmission of polarized paraxial light beams at a plane
dielectric interface. The field transformations taking into account a finite beam width are …

Spin optics provides a route to control light, whereby the photon helicity (spin angular
momentum) degeneracy is removed due to a geometric gradient onto a metasurface. The …
