We review thin micro-optics components with nanostructured microreliefs intended to control
the polarization and phase of laser light. These components include transmission and …

In this paper, the tight focusing of high-order cylindrical vector beams (beams with
polarization singularity) was investigated. Using the Richards-Wolf formalism, there were …

By simulating tight focusing of vector beams with azimuthal polarization of fractional order 0<
m< 1 (m= 1 is the azimuthal polarization; m= 0 is the linear polarization), it is shown that the …

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 …

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 …

In ordinary circumstances the highest frequency present in a wave is the highest frequency
in its Fourier decomposition. It is however possible for there to be a spatial or temporal …

Quasi-non-diffracting beams are attractive for various applications, including optical
manipulation, super-resolution microscopes, and materials processing. However, it is a …

In this study, direct laser writing (DLW) lithography is employed to fabricate a large-scale
and high-numerical-aperture super-oscillatory lens (SOL), which is capable of achieving a …

It is shown theoretically and numerically that circularly and linearly polarized incident beams
produce at the tight focus identical circularly symmetric distributions of an on-axis energy …
