In this paper, we demonstrate the generation of different singularity lattices consisting of only V-points or only C-points using a versatile method based on double phase modulation. Overcoming the inherent problems with interferometry, the proposed approach utilizes a spatial light modulator for modulating the phase distributions of evaluated interference field into the light beams. This concept is used in a single optical set-up to realize different types of lattice fields of C-points and V-points. The proposed set-up not only reduces the complexity and alignment issues but alleviates the need of using a polarization controlling element such as a Q-plate.

通过双相调制形成极化奇异点阵

在本文中，我们演示了使用基于双相调制的通用方法生成仅由V点或仅由C点组成的不同奇异点阵的方法。为了克服干涉测量法固有的问题，所提出的方法利用空间光调制器来将评估的干涉场的相位分布调制到光束中。此概念用于单个光学装置中，以实现C点和V点的不同类型的晶格场。所提出的设置不仅减少了复杂性和对准问题，而且减轻了使用诸如Q板之类的偏振控制元件的需要。
