摘要
提出了基于琼斯矩阵的矢量涡旋光偏振态的庞加莱球表示方法。应用琼斯矩阵法建立了基于圆偏振涡旋基矢的矢量涡旋光束的电场矢量分布模型。分析了光束的拓扑荷和方位角对矢量涡旋光束偏振态的影响,给出了不同拓扑荷的矢量涡旋光束偏振态的庞加莱球表示方法。与传统的利用斯托克斯参量建立的高阶庞加莱球表示方法相比,矢量涡旋光束描述方法的物理意义更加清晰明了。求解电场矢量的亥姆霍兹方程,发现该光束电场矢量的振幅服从贝塞尔-高斯分布。
A Poincaré sphere （PS） representation for states of polarization （SOPs） of vector vortex beams based on Jones matrix is proposed. For the vector vortex beams which are combined with two circular polarization optical vortexes of opposite topological charges, a distribution model of electric field vector is developed by using Jones matrix. Two influencing factors of SOPs are educed： the topological charge and azimuthal angle. And the PS representation for SOPs with different topological charges is presented. Compared with the higher-order PS constructed with Stokes parameters, the physical meaning of this description method for vector vortex beams is much clearer. After a rigorous vector Helmholtz equation analysis, the amplitude of vector vortex beams is found to follow Bessel-Gauss distribution.
