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 …

As an intrinsic property of light, angular momentum has always been an important research
object of light field. In the past few years, the interactions between spin angular momentum …

Structured light refers to the ability to tailor optical patterns in all its degrees of freedom, from
conventional 2D transverse patterns to exotic forms of 3D, 4D, and even higher-dimensional …

Beams carrying orbital-angular-momentum (OAM) have gained much interest due to their
unique amplitude and phase structures. In terms of communication systems, each of the …

Active engineering and modulation of optical spectra in a remote and fully reversible light is
urgently desired in photonics, chemistry, and materials. However, the real-time regulation of …

This paper explores the data carrying capacity enhancement in free space optics (FSO)
transmission systems by employing orbital angular momentum (OAM) multiplexing …

As an alternative degree of freedom for wireless communications, orbital angular momentum
(OAM) multiplexing and demultiplexing can be applied to achieve higher communication …

Increasing the information capacity of communication channels is a pressing need, driven by
growing data demands and the consequent impending data crunch with existing modulation …

Electron beam sha** by sculpted thin films relies on electron–matter interactions and the
wave nature of electrons. It can be used to study physical phenomena of special electron …

We report an experimental proof of concept for speckle-based one-to-three non-line-of-sight
(NLOS) free space optical (FSO) communication channels employing structured light shift …
