Abstract

The complex vector mode is a general state in which light is inseparable in spatial and polarization degrees of freedom. Controlling the spatial distribution of complex vector modes with different parameters is vital. Herein, we propose a method to generate the multi-shaped perfect vector beam (MPVB) based on a digital micromirror device (DMD) for the first time. Owing to the high refresh rate and polarization independence of DMD itself, we designed and built a novel interference experimental setup based on DMD and half-wave plate. Firstly, we realized the theoretical characterization of arbitrary polarization distributions on the cross-section of the MPVB. Subsequently, we achieved flexible control of MPVBs at arbitrary positions on the higher-order Poincaré sphere and hybrid-order Poincaré sphere, and the vector quality factor (VQF) is calculated based on Stokes parameters. This technique provides a vector beam generation and manipulation method in two-dimensional parameter space and may find important application in optical imaging, microscopy, and optical tweezers.

多形状的完美矢量光束操纵

复矢量模式是光在空间自由度和偏振自由度上不可分的一般状态。控制不同参数的复矢量模的空间分布至关重要。本文首次提出了一种基于数字微镜器件（DMD）的多形状完美矢量光束（MPVB）生成方法。由于DMD本身具有较高的刷新率和偏振无关性，我们设计并建立了一种基于DMD和半波片的新型干涉实验装置。首先，我们实现了MPVB截面上任意偏振分布的理论表征。随后，在高阶poincar球和混合阶poincar球上实现了MPVBs在任意位置的柔性控制，并基于Stokes参数计算了矢量质量因子（VQF）。该技术提供了一种二维参数空间的矢量光束生成和操作方法，在光学成像、显微镜和光镊等领域具有重要的应用前景。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
