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 …

The paper briefly presents some essential concepts and features of light fields with strong
spatial inhomogeneity of amplitude, phase, polarization, and other parameters. It contains a …

Structured light refers to the generation and application of custom light fields. As the tools
and technology to create and detect structured light have evolved, steadily the applications …

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 …

Vector modes are spatial modes that have spatially inhomogeneous states of polarization,
such as, radial and azimuthal polarization. In this work, the spatially inhomogeneous states …

In this work, it is experimentally demonstrated that the nonseparability of vector beams (eg,
radial and azimuthal polarization) can be used to encode information for optical …

As they travel through space, some light beams rotate. Such light beams have angular
momentum. There are two particularly important ways in which a light beam can rotate: if …

High-dimensional entanglement with spatial modes of light promises increased security and
information capacity over quantum channels. Unfortunately, entanglement decays due to …

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 …

Quantum mechanics is now a mature topic dating back more than a century. During its
scientific development, it fostered many technological advances that now are integrated into …
