论文摘要
我们提出了一种通过Pancharatnam-Berry阶段产生Monstar奇异性的方法，这是通过两个自由形式的深色空心梁的连贯的共线叠加，$ ffdh^{m} _ {q} _ {q} $，拓扑费$ q $，和对称$ m $ m $。 FFDH梁是用开发的封闭曲线的几何参数生成的，以获得局部极化方位角的不均匀旋转速率并生成MONSTAR模式。我们报告空间变化的极化模式：径向和方位角样，柠檬和类似于对称脱节的柠檬和星形，以及不对称的MONSTAR披露。我们提出理论和测量，并在两者之间找到极好的一致性。
We present a method to generate monstar singularities via Pancharatnam-Berry phase by the coherent collinear superposition of two Free-Form Dark Hollow beams, $FFDH^{m}_{q}$, of topological charge $q$, and order of symmetry $m$. FFDH beams are generated with the geometrical parameters of a closed curve exploited to obtain a nonuniform rotation rate of the local polarization azimuth and generate monstar patterns. We report space-variant polarization patterns: radial- and azimuthal-like, lemon- and star-like for symmetric disclinations, and the asymmetric monstar disclination. We present theory and measurements, and find excellent agreement between the two.
