Paper Abstract

In this paper, we study and compare the propagation properties of both scalar and vector vortex beams through turbulent atmosphere. The atmosphere turbulence effect is simulated with von Kármán power spectrum model using index of refraction structure parameter, Cn2, values ranging from 10-14 m-2/3 to 10-12 m-2/3. For different propagation distances, the irradiance pattern and the scintillation index are computed for a fundamental Gaussian beam, a scalar vortex with topological charge of +1 and a radially polarized beam under the same turbulence condition. The results demonstrate the advantages of using vector vortex to mitigate atmospheric effects. In addition, it is found by analyzing the polarization pattern of the transmitted vector vortex beams, that they may find applications in free space communications and remote sensing.
