Multicasting is necessary when distributing signals between multiple users. In this Letter, we demonstrate an orbital angular momentum (OAM) encoding-based free-space one-to-many multicasting link, where digital signals are encoded into a series of t

A phase-diffractive optical element is designed to measure the topological charge of optical vortices. We use the scalar diffraction theory to calculate the far-field diffraction patterns. The simulation results show that almost all of the power of t

We theoretically and experimentally demonstrate a scheme to monitor the weight of a single orbital angular momentum (OAM) channel for coaxial multiplexed optical vortices with large mode spacing. A specially designed holographic grating is illuminate

By utilizing the property of the phase’s rapid solution of the Gerchberg–Saxton algorithm, we experimentally demonstrate a scheme to correct distorted Bessel–Gauss beams resulting from inhomogeneous media as weak turbulent atmosphere with good

Perfect polarization vortices (PPVs) are a type of vector beam with a diameter independent of the polarization order. In this paper, an experimental method is proposed to generate PPVs with an anisotropic polarization distribution. First, a specially

A scheme to simultaneously detect topological charges of coaxial multiplexed perfect vortices, is proposed experimentally. The coaxial multiplexed perfect vortices can be divided and transformed into 0-th order Bessel-Gauss beams in different diffrac

Orbital angular momentum (OAM), a new dimension of photons, has potentials in lots of domains as high-dimensional data coding/decoding. Here we experimentally demonstrate a free-space data transmission system based on 8 bits multi-state OAM shift key

In this paper, we propose a Sagnac-like scheme, to transform Laguerre–Gaussian (LG) beams into vector beams. The experimental apparatus of our scheme consists of a polarized beam splitter, two reflectors, and a quarter-wave plate (QWP). Firstly, ho

We propose a scheme that uses a probe Gaussian beam and the Gerchberg–Saxton (GS) algorithm to realize the pre-turbulence compensation of beams carrying orbital angular momentum (OAM). In the experiment, spatial light modulators are utilized to sim
