矢量束包含复杂的偏振结构，在偏振和空间自由度上本质上是不可分离的。矢量束的空间变化偏振使其在从经典物理到量子物理的各个领域都有了重要的应用。在这项研究中，我们设计并实现了一种基于马赫-曾德尔干涉仪的装置，通过操纵组合螺旋相位板的马赫-曾德尔干涉仪系统中的两个本征态，实现了高阶庞加莱球面任意点的矢量光束。我们演示了不同类型的高阶庞加莱光束的产生，包括位于高阶庞加莱球的经纬点上的光束，垂直条L垂直条=1和垂直条L垂直条=2的贝尔态光束，以及L=16的极高阶径向偏振光束等，实验获得了高质量和高精度的矢量光束，并通过实际性能证明了该装置的灵活性、可行性和高效率。(C)OSA开放获取出版协议条款下的2020年美国光学学会
Vector beams contain complex polarization structures and they are inherently nonseparable in the polarization and spatial degrees of freedom. The spatially variant polarizations of vector beams have enabled many important applications in a variety of fields ranging from classical to quantum physics. In this study, we designed and realized a setup based on Mach-Zehnder interferometer for achieving the vector beams at arbitrary points of higher-order Poincare sphere, through manipulating two eigenstates in the Mach-Zehnder interferometer system with the combined spiral phase plate. We demonstrated the generation of different kinds of higher-order Poincare beams, including the beams at points on a latitude or longitude of higher-order Poincare sphere, Bell states for vertical bar l vertical bar = 1 and vertical bar l vertical bar = 2, radially polarized beams of very high order with l = 16, etc. Vector beams of high quality and good accuracy are experimentally achieved, and the flexibility, feasibility and high efficiency of the setup are demonstrated by the practical performance.
