Interest in the multiple facets of optical vortices has flourished in the last three decades. This
review examines the basic research and applications of the interplay between optical …

Since the second half of the 20th century, ideas to develop methods for the formation of
optical vortices (OVs) or OV beams–regions of circular motion of energy flow in an …

Twisted light carries a nonzero orbital angular momentum, that can be transferred from light
to electrons and particles ranging from nanometers to micrometers. Up to now, the interplay …

Optical vortex is a type of structured beam with helical phase wavefronts that carry orbital-
angular momentum (OAM) with different topological charge numbers. Optical vortex beams …

We demonstrate the generation of far-field propagating optical beams with a desired orbital
angular momentum by using a smooth optical-mode transformation between a plasmonic …

The electric field of an optical vortex (OV) beam displays a specific winding pattern
determined by its spatial variation and angular momentum. An OV beam can serve as a …

Recent studies have revealed that chiral phonons resonantly excited by ultrafast laser
pulses carry magnetic moments and can enhance the magnetization of materials. In this …

The microscopic mechanism of the light-matter interactions that induce orbital angular
momentum (OAM) in electromagnetic fields is not thoroughly understood. In this work, we …

Photonic spin‐orbit interactions (PSOIs) in nanostructures have attracted much interest in
nanophotonics, which provide a new paradigm to enhance light‐matter interactions and …

Surface plasmon waves carry an intrinsic transverse spin, which is locked to its propagation
direction. Apparently, when a singular plasmonic mode is guided on a conic surface this …
