作为新型结构光束的一类,全庞加莱球光束因其横截面上自旋角动量和轨道角动量发生耦合,近年来在自由空间光通信领域内受到广泛关注.然而,传输信道中的大气湍流将产生诸如光束扩展、漂移、光强闪烁等严重影响,进而限制光通信系统性能.结合随机相位屏,对具有“C”型偏振奇点的全庞加莱球光束、\'\'V“型偏振奇点的柱矢量光束和均匀偏振的标量涡旋光束在湍流大气中的传播进行大量的数值模拟.归一化光强相关系数和模式纯度被用于研究杂合庞加莱球表面不同位置处表征的全庞加莱球的稳定性.结果 表明,相较于具有相似偏振拓扑荷和光强分布的柱矢量光束以及标量涡旋光束而言,坐标位于南半球的全庞加莱球光束在弱湍流和中湍流(r0=0.5 m,0.125 m)下具有较高稳定性.而在强湍流下(r0=0.056 m),优势区域缩小至2σ∈[5π/32,0](纬度坐标).上述结果将为自由空间远距离通信中传输介质的选取提供重要依据并进一步促进通信质量的提升.”,\"Full Poincaré beams,as a more complicated class of novel structural beams,lead to impressive demonstrations recently in Free-Space Optical Communication (FSOC) due to the coupling of spin and orbital angular momentum in the cross section.However,a noteworthy limiting factor of FSOC system in this process is the varying atmospheric turbulence which results in beam expansion,drift,light intensity scintillation and other severe effects.Massive numerical simulations on turbulent atmospheric propagation of full Poincaré beams with C-point polarization,cylindrical vector beams with V-point polarization and homogeneous scalar polarized vortex beams through random phase screens were demonstrated.In this process,normalized correlation coefficient and mode purity were proposed to explore the robustness of full Poincaré beams on different locations of hybrid-order Poincaré sphere.The results show that full Poincaré beams with coordinates located in the southern hemisphere remain high robustness under weak and moderate turbulence (r0=0.5 m,0.125 m) compared with cylindrical vector beams and scalar vortex beams with similar topological charges and intensity distribution.While the dominant area shrinks to 2σ∈[5π/32,0](latitude coordinates) under strong turbulence (r0=0.056 m).These results will promote the selection of robust transmission media and the development of transmission quality in fiee-space communications with long-distance.
