Structured light, especially beams carrying orbital angular momentum (OAM), has gained
much interest due to its unique amplitude and phase structures. In terms of communication …

Orbital angular momentum (OAM), which describes tailoring the spatial physical dimension
of light waves into a helical phase structure, has given rise to many applications in optical …

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 …

Mobile communications have been undergoing a generational change every ten years or
so. However, the time difference between the so-called “G's” is also decreasing. While fifth …

With inherent orthogonality, both the spin angular momentum (SAM) and orbital angular
momentum (OAM) of photons have been utilized to expand the dimensions of quantum …

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 …

The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

Since its discovery, quantum entanglement has challenged some of the best established
views of the world: locality and reality. Quantum technologies promise to revolutionize …

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 …

Vortex beam carrying orbital angular momentum (OAM) has been widely explored in optical
and microwave regions attributed to its potential characteristics in communication systems …
