Propagation dynamics of autofocusing Mathieu vortex beams through atmospheric turbulence

Abstract

We demonstrate the propagation dynamics of autofocusing Mathieu vortex beams (AFMVBs) through atmospheric turbulence in this work. The multi-phase screen framework has been relied on to model turbulent atmosphere. For better evaluation, a series of assessment approaches are proposed to quantify the transmission performance of the beams in free space optical links. The simulation results indicate that beam quality degrades with increasing propagation distance and turbulence strength, but it exhibits a fascinating selectivity in the correlation between beam orders and different performance metrics. This study would pave new avenues for potential application of autofocusing beams in optical communication.
