Optical trapping describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trapping with a single beam, this is …

Optically variable devices (OVDs) are in tremendous demand as optical indicators against
the increasing threat of counterfeiting. Conventional OVDs are exposed to the danger of …

The term Poincaré beam, which describes the space-variant polarization of a light beam
carrying spin angular momentum (SAM) and orbital angular momentum (OAM), plays an …

Allowing subwavelength-scale-digitization of optical wavefronts to achieve complete control
of light at interfaces, metasurfaces are particularly suited for the realization of planar phase …

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 …

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 …

Optical elements that convert the spin angular momentum (SAM) of light into vortex beams
have found applications in classical and quantum optics. These elements—SAM-to–orbital …

Progress in optical manipulation has stimulated remarkable advances in a wide range of
fields, including materials science, robotics, medical engineering, and nanotechnology. This …

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

Harnessing linear and angular momenta of light is one of the cornerstones in modern optics
