We propose and experimentally demonstrate a novel interferometric approach to generate arbitrary cylindrical vector beams on the higher order Poincaré sphere (HOPS). Our scheme is implemented by collinear superposition of two orthogonal circular polarizations with opposite topological charges. By modifying the amplitude and phase factors of the two beams, respectively, any desired vector beams on the HOPS with high tunability can be acquired. Our research provides a convenient way to evolve the polarization states in any path on the high order Poincaré sphere.
我们提出并通过实验证明了一种在高阶庞加莱球面上生成任意圆柱矢量光束的新型干涉方法。我们的方案是通过具有相反拓扑电荷的两个正交圆偏振的共线叠加来实现的。通过分别修改两束光的振幅和相位因子,可以获得高阶庞加莱球面上具有高可调性的任何所需矢量光束。我们的研究为在高阶庞加莱球面上的任何路径上演变偏振态提供了一种便捷的方法。
