Performance of hollow hyperbolic sinusoidal Gaussian beam in weak turbulent optical communication links

The performance of hollow hyperbolic sinusoidal Gaussian beam (HHsGB) propagating in weak
turbulent optical communication link is examined by analysing the beam scintillation indices. System
parameters’ effect on point-like and aperture-averaged scintillation index values is investigated. The
obtained results show that HHsGBs with small source sizes improve the link performance by reducing
the scintillation level. In communication systems with a big receiver aperture radius, HHsGBs with
high orders significantly minimize the scintillation level. Thus, the provided results will have
significant potential in improving free-space optical communication performance in a wide range of
applications.
