Cylindrical vector beams (CVBs), which possess polarization distribution of rotational symmetry on the transverse plane, can be developed in many optical technologies. Conventional methods to generate CVBs contain redundant interferometers or need to switch among diverse elements, thus being inconvenient in applications containing multiple CVBs. Here we provide a passive polarization-selective device to substitute interferometers and simplify generation setup. It is accomplished by reversing topological charges of orbital angular momentum based on a polarization-selective Gouy phase. In the process, tunable input light is the only condition to generate a CVB with arbitrary topological charges. To cover both azimuthal and radial parameters of CVBs, we express the mapping between scalar Laguerre–Gaussian light on a basic Poincaré sphere and CVB on a high-order Poincaré sphere. The proposed device simplifies the generation of CVBs enormously and thus has potential in integrated devices for both quantum and classic optical experiments.

由偏振选择性 Gouy 移相器实现的任意柱面矢量光束生成

圆柱矢量光束 (CVB) 在横向平面上具有旋转对称的偏振分布,可以在许多光学技术中开发。生成CVBs的传统方法包含冗余干涉仪或需要在不同元素之间切换,因此在包含多个CVBs的应用中不方便。在这里,我们提供了一种无源偏振选择装置来替代干涉仪并简化生成设置。它是通过基于极化选择性 Gouy 相位反转轨道角动量的拓扑电荷来实现的。在这个过程中,可调输入光是产生具有任意拓扑电荷的 CVB 的唯一条件。为了涵盖 CVB 的方位角和径向参数,我们表达了基本庞加莱球上的标量拉盖尔-高斯光和高阶庞加莱球上的 CVB 之间的映射。所提出的设备极大地简化了 CVB 的生成,因此在用于量子和经典光学实验的集成设备中具有潜力。
