Superimposed orbital angular momentum mode of multiple Hankel–Bessel beam propagation in anisotropic non-Kolmogorov turbulence

Chinese Optics Letters, 2016
Mathematical models for the superimposed orbital angular momentum (OAM) mode of multiple Hankel–Bessel (HB) beams in anisotropic non-Kolmogorov turbulence are developed. The effects of anisotropic turbulence and source parameters on the mode detection spectrum of the superimposed OAM mode are analyzed.

Beam Wander Effects on Scintillation Theory of Gaussian Beam through Anisotropic Non-Kolmogorov Atmospheric Turbulence for Optical Wireless Communication

2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018
Beam wander effects have been discussed as the main reason for the failure of the first-order Rytov approximation to properly predict the scintillation index of Gaussian beam through the atmospheric turbulent channel of optical wireless communication. This paper investigates the beam wander effects on scintillation theory of Gaussian beam based on the ...

Performance of wireless optical communication systems based on polarization shift keying modulation over anisotropic non-Kolmogorov turbulence

2018 Asia Communications and Photonics Conference (ACP), 2018
We investigated the performance of wireless optical communication systems with polarization shift keying modulation when the atmospheric turbulence is anisotropic. Based on the unified theory of polarization and coherence, the characteristic of polarization crosstalk on propagation was shown.

Comparison of Gaussian and Laguerre–Gaussian beams propagating through anisotropic non-Kolmogorov atmospheric turbulence

Applied Optics
The performance of two types of optical beams in anisotropic turbulence is compared with respect to elliptical distortion, power retention, and beam broadening. The considered beams are the conventional Gaussian beam and the Laguerre–Gaussian (LG) beam with azimuthal mode indices (l=1) and (l=2).
