Performance Characteristics of Perfect Vortex Beam Operating as Free-space Optical Communication Links

This paper explores the propagation characteristics of perfect vortex beams (PVBs) in atmospheric turbulence and evaluates their performance as optical communication links. The aperture averaged scintillation index of PVBs under turbulent conditions is calculated, along with the mean signal-to-noise ratio (SNR) and mean bit error rate (BER) when employed as optical links. The influence of various PVB parameters on the aperture averaged scintillation index, mean SNR, and mean BER is systematically analyzed. The findings of this study are expected to aid in the advancement of optical systems operating in atmospheric turbulence conditions.
