In recent years, vortex beams with orbital angular momentum (OAM) have attracted more
and more attention. The wavefront of the OAM beams is helical, the intensity at the center of …

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 …

Orbital angular momentum (OAM), one of the most recently discovered degrees of freedom
of light beam field has fundamentally revolutionized optical physics and its technological …

In this paper, we study the effect of turbulent atmosphere for a new type of Bessel-like beams
family by considering a generalized spiraling Bessel beam (GSBB) created by illuminating a …

Perfect optical vortices (POVs) are beams whose topological charges are independent of
radius, unlike conventional optical vortices. POVs are the Fourier transformation of Bessel …

In this paper, we consider using a binary curved fork grating not only for the simultaneous
formation of several Bessel vortex beams but also for detecting the presence of angular …

Based on the process of the Fresnel diffraction, the possibility of generating a new type of
laser beams family by illuminating a curved fork-shaped hologram, with an input …

Based on the Fresnel diffraction integral formula, the diffraction of Laguerre-Bessel-
Gaussian (LBG) beam by a helical axicon is investigated. The expressions of the amplitude …

Multiplexing a signal using the largest number of freedom degrees is an important task in the
field of optical information transmission. Variations in the beams amplitude-phase structure …

The paper investigates the performance of a tilted vortex phase lens, quantized at a given
level and allowing the generation of specified local maxima both on the optical axis and off …
