Numerical investigation of performance of mirrored Bessel beam in turbulence

Abstract

We study scintillation and bit error rate performance of mirrored Bessel beams through turbulent atmosphere in this article. We benefit from numerical method to model the atmosphere. Since scintillation plays a vital role in optical wireless applications, reduction in this term provides better performance in these systems. Bearing in mind this, our results indicate that it is possible to decrease scintillation by increasing beam order to three when strong turbulent conditions are satisfied. In addition, we observe that argument of Bessel beam has more dominant role than beam order in moderate turbulence. Lastly, mirroring brings us a slight advantage in case of bit error rate. Results of this study can be beneficial for optical link designers.

Ince–Gaussian beams propagation through turbulent atmospheric medium

“…The theoretical investigations on the propagation of beams in turbulent atmosphere are generally carried out within the paraxial approximation and the Rytov method (Andrews and Phillips 2005). Based on the extended Huygens-Fresnel integral formula, the propagation study of different beams such as truncated Bessel Gaussian beams (Cang and Zhang 2010), Bessel modulated Gaussian beams (Belafhal et al 2011), Hypergeometric Gaussian beams (Khannous et al 2015), apertured Lommel Gaussian beams (Ez-zariy et al 2016), Hollow Gaussian beams (Khannous et al 2016), Pearcey-Gaussian beams (Boufalah et al 2016), Generalized spiraling Bessel beams (Saad and Belafhal 2017), dark and antidark Gaussian beams (Yaalou et al 2019), generalized Bessel-Laguerre Gaussian beams (Boufalah et al 2022) , mirrored Bessel beam (Bayraktar et al 2023) have been investigated. In these works, the authors have examined the effects of beam profiles and turbulent atmosphere parameters on the transformation of the considered beams by the turbulent atmosphere.…”
