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 …

Spatial mode (de) multiplexing of orbital angular momentum (OAM) beams is a promising
solution to address future bandwidth issues, but the rapidly increasing divergence with the …

Twisted photons can be used as alphabets to encode information beyond one bit per single
photon. This ability offers great potential for quantum information tasks, as well as for the …

Orbital angular momentum (OAM) has aroused a widespread interest in many fields,
especially in telecommunications due to its potential for unleashing new capacity in the …

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 …

With the ever-increasing demand for data and the radio frequency spectrum becoming
congested, free space optics (FSO) may find a niche for situations where fiber is too …

Vector vortex beams are structured states of light that are nonseparable in their polarisation
and spatial mode, they are eigenmodes of free-space and many fiber systems, and have the …

Spatial modes of light can potentially carry a vast amount of information, making them
promising candidates for both classical and quantum communication. However, the …

Time, polarization, and wavelength multiplexing schemes have been used to satisfy the
growing need of transmission capacity. Using space as a new dimension for communication …
