复合类贝塞尔光场中偏振奇性的操纵传播与演化
Manipulating propagation and evolution of polarization singularities in composite Bessel-like fields
摘要：
具有偏振奇异性的结构光场因其在传输过程中保持拓扑不变性的能力而受到广泛关注。在过去的20年里，在物理系统的数学描述、产生和检测技术、传播动力学和应用等方面取得了许多进展。然而，最关键和最困难的任务之一仍然是操纵PS与多个自由度，特别是在三维（3D）定制的光场。提出并证明了在复合矢量光场上叠加具有正交偏振态的类贝塞尔模所得到的纵向PS线。场中嵌入的PS可以被操纵以沿着任意轨迹稳健地传播，或者在3D空间中的按需位置处相互湮灭、复活和变换，从而允许灵活地定制复杂的PS拓扑形态和强度图案。我们的研究结果可以刺激对奇异光学的进一步研究，并有助于微操作，微结构制造和光学加密等应用。
英文摘要：
Structured optical fields embedded with polarization singularities (PSs) have attracted extensive attention due to their capability to retain topological invariance during propagation. Many advances in PSs research have been made over the past 20 years in the areas of mathematical description, generation and detection technologies, propagation dynamics, and applications. However, one of the most crucial and difficult tasks continues to be manipulating PSs with multiple degrees of freedom, especially in three-dimensional (3D) tailored optical fields. We propose and demonstrate the longitudinal PS lines obtained by superimposing Bessel-like modes with orthogonal polarization states on composite vector optical fields (VOFs). The embedded PSs in the fields can be manipulated to propagate robustly along arbitrary trajectories, or to annihilate, revive, and transform each other at on-demand positions in 3D space, allowing complex PSs topological morphology and intensity pattern to be flexibly customized. Our findings could spur further research into singular optics and help with applications such as micromanipulation, microstructure fabrication, and optical encryption.
