Thirty years ago, Coullet et al. proposed that a special optical field exists in laser cavities
bearing some analogy with the superfluid vortex. Since then, optical vortices have been …

Controlling the various degrees‐of‐freedom (DoFs) of structured light at both quantum and
classical levels is of paramount importance in optics. It is a conventional paradigm to treat …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Structured light recently highlighted the higher-dimensional control with many tailored
degrees of freedom (DoFs) such as amplitude, wavelength, polarization, and orbital angular …

Structured light is derived from the ability to tailor light, usually referring to the spatial control
of its amplitude, phase, and polarization. Although a venerable topic that dates back to the …

In recent times, the optical-analogous skyrmions, topological quasiparticles with
sophisticated vectorial structures in light, have received an increasing amount of interest …

The Doppler effect is a universal wave phenomenon that has spurred a myriad of
applications. In early manifestations, it was implemented by interference with a reference …

Structured light is routinely used in free-space optical communication channels, both
classical and quantum, where information is encoded in the spatial structure of the mode for …

Vector vortex beams are conventionally created as the superposition of orbital angular
momentum (OAM) modes with orthogonal polarizations, limiting the available degrees of …

Structured light has become topical of late, where controlling light in all its degrees of
freedom has offered novel states of light long predicted, enhanced functionality in …
