Vector beams, and in particular vector vortex beams, have found many applications in recent
times, both as classical fields and as quantum states. While much attention has focused on …

Axicon is a versatile optical element for forming a zero-order Bessel beam, including high-
power laser radiation schemes. Nevertheless, it has drawbacks such as the produced …

Herein, we have discussed three major methods which have been generally employed for
the generation of optical beams with orbital angular momentum (OAM). These methods …

We show theoretically and numerically that an n-th order vector light field containing the
central V-point singularity of indefinite linear polarization with polarization singularity index …

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 …

Beam splitters play important roles in several optical applications, such as interferometers,
spectroscopy, and optical communications. In this study, we propose and numerically …

In this study, we propose a new approach to construct metasurfaces for the generation of
inverse energy flux near the optical axis. We derive new equations intended to create …

We propose a metalens that forms an abruptly autofocusing cylindrically polarized laser
beam. The main principle of the metalens is based on combining two elements: a …

A fast and reliable method for the fabrication of polarization modifying devices using
femtosecond laser is reported. A setup based on line focusing is used for the generation of …

Complex polarization-phase transformations that are realized using easy-to-manufacture
optical elements are considered. The manufacturing technology of such elements is based …
