The orbital angular momentum (OAM) of light has been implemented as an information
carrier in OAM holography. Holographic information can be multiplexed in theoretical …

We report the enhanced experimental measurement of tiny rotational angles using two
conjugate OAM modes upon rotation of a Dove prism. The two conjugate OAM modes …

We construct an experimental measurement system for rotation vibration signal detection
using the orbital angular momentum (OAM) of light in a Sagnac interferometer. Inputting light …

We experimentally investigate the second-harmonic generation of a high-order Laguerre–
Gaussian (LG) mode under the quasi-phase-matching (QPM) configuration. First, we …

A phenomenological description of nondegenerate and degenerate three-wave mixing in
the bulk of an isotropic chiral medium is given for the wide class of fundamental light beams …

The article is devoted to issues related to the propagation and transformation of vortexes in
the optical range of frequency. Within the framework of the traditional and modified model of …

The orbital angular momentum (OAM) of a vortex beam has already found significant
potential applications in both quantum and classical communication systems. In this study, a …

We theoretically study the optical parametric amplification (OPA) process seeded by a
Laguerre–Gaussian (LG) mode. Based on the nonlinear coupled-wave equations, we …

In this paper, a kind of layered metastructure (LMS) is proposed by stacking multi-layer
dielectric plates. By adjusting the dielectric constant of medium A (set as εi), the Brewster …

Structured light beams, such as optical vortices, vector beams, and non-diffracting beams,
have been recently studied in a variety of fields, such as optical manipulations, optical …
