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 the last three decades, light's orbital angular momentum (OAM) has been of great interest
because it has unique characteristics that make it sought after in many research fields …

A new technique for measuring the degenerate spectra of optical vortices and orbital
angular momentum (OAM) of singular beams is theoretically studied and experimentally …

Structured light carrying optical vortices have gained significant attention in information
security as they offer high-dimensional orthogonal states for encoding. These states are …

In this paper, we investigate the generation and controlling of the optical vortex beam using
a dye-doped liquid crystal (DDLC) cell. The spatial distribution of the quasi-sinusoidal …

Structured optical fields, such as cylindrical vector (CV) and orbital angular momentum
(OAM) modes, have attracted considerable attention due to their polarization singularities …

We investigate a method for the generation and measurement of high-order optical vortices
(OVs) by using the cross phase (CP), which is applied to implement interconversion …

The recognition, decoding and tracking of vortex patterns is of increasing importance in
many fields, ranging from the astronomical observations of distant galaxies to turbulence …

In this paper, we explore the use of an optical correlation technique to decompose different
radial as well as azimuthal order modes of Laguerre Gaussian (LG) beams. We …

The motion of noncircular two-dimensional vortices is shown to depend on a form of
coupling between vortex ellipticity and the gradient of fluid density. The approach is based …
