Modal decomposition of light has been known for a long time, applied mostly to pattern
recognition. With the commercialization of liquid-crystal devices, digital holography as an …

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 …

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 …

Existing for almost four decades, liquid crystal on Silicon (LCOS) technology is rapidly
growing into photonic applications. We review the basics of the technology, from the wafer to …

Vector beams have the defining property of nonseparable spatial and polarization degrees
of freedom and are now routinely generated in the laboratory and used in a myriad of …

We propose the concept of perfect vectorial vortex beams (VVBs), which not merely have
intensity profile independent of the polarization order and the topological charge of spiral …

A quantitative analysis of optical fields is essential, particularly when the light is structured in
some desired manner, or when there is perhaps an undesired structure that must be …

Characterizing the orbital-angular-momentum (OAM) modes is critically important for OAM-
encoded data transfer. However, traditional characterizing approaches rely on either …

We experimentally demonstrate an efficient information transmission technique using
Laguerre Gaussian (LG) modes. This technique is based on multiplexing and demultiplexing …

Light beams that carry orbital angular momentum are often approximated by modulating an
initial beam, usually Gaussian, with an azimuthal phase variation to create a vortex beam …
