Propagation of vortex symmetric Airy beam in the turbulent link

The vortex symmetric Airy beam (VSAB) which couples the autofocusing symmetric Airy beam (SAB) and topological charge can provide new possibilities for the optical carrier of free space optical communication (FSOC). This paper focuses on the performance of VSAB propagating through turbulent link. Based on the wave optics simulation, the model of VSAB propagating in atmospheric turbulence is constructed. By using the model, the evaluation parameters light intensity and aperture averaged scintillation of VSAB are calculated. The influence of different beam parameters on the characteristics of VSAB propagation in turbulent link is investigated. The results show that the VSAB with small decaying factor, small transverse length scales and less topological charge has more advantage in turbulence resistance.
