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 …

Twisted light, an unbounded set of helical spatial modes carrying orbital angular momentum
(OAM), offers not only fundamental new insights into structured light–matter interactions, but …

We introduce a new paradigm for generating high-purity vortex beams with metasurfaces. By
applying optical neural networks to a system of cascaded phase-only metasurfaces, we …

Recent advances in wavefront shaping have enabled complex classes of Structured Light
which carry spin and orbital angular momentum, offering new tools for light-matter …

There is a growing interest in structured light, especially orbital angular momentum (OAM)
beams, due to its unique amplitude and phase structure. Multiple orthogonal OAM beams …

On‐chip integrated micro‐and nanoscale vortex lasers are key elements for addressing the
exponentially growing demand for information capacity. Although tunable vortex microlasers …

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 …

Since the second half of the 20th century, ideas to develop methods for the formation of
optical vortices (OVs) or OV beams–regions of circular motion of energy flow in an …

This book is devoted to the consideration of unusual laser beams–vortex or singular beams.
It contains many numerical examples, which clearly show how the phase of optical vortices …

Twisted light, with spatially varying phase or polarization, has given rise to various
applications, such as micro-particle manipulation, optical communication, and quantum …
