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 paper briefly presents some essential concepts and features of light fields with strong
spatial inhomogeneity of amplitude, phase, polarization, and other parameters. It contains a …

Recently, spatiotemporal optical vortex pulses carrying a purely transverse intrinsic orbital
angular momentum were generated experimentally [Optica 6, 1547 (2019) OPTIC8 2334 …

Both classical and quantum waves can form vortices: entities with helical phase fronts and
circulating current densities. These features determine the intrinsic orbital angular …

Optical activity is conventionally understood as a natural difference in the optical responses
of chiral materials with opposite handedness. It stems from the quantised spin angular …

We review optical phenomena associated with the internal energy redistribution which
accompany propagation and transformations of monochromatic light fields in homogeneous …

Motivated by recent progress in the generation of optical spatiotemporal vortex pulses
(STVPs), there is a theoretical discussion about the transverse orbital angular momentum …

We show that a class of vector vortex beams possesses a topological property that derives
both from the spatially varying amplitude of the field and its varying polarization. This …

We present a brief introduction to the orbital angular momentum of light, the subject of our
theme issue and, in particular, to the developments in the 13 years following the founding …

We review the geometrical-optics evolution of an electromagnetic wave propagating along a
curved ray trajectory in a gradient-index dielectric medium. A Coriolis-type term appears in …
