用数字示波器产生和表征复矢量模

Generation and characterization of complex vector modes with digital micromirror devices

Xiaobo Hu, Carmelo Rosales Guzman

摘要:

具有空间变化偏振分布的复矢量光模式最近已经成为热门话题,使得在许多研究领域中能够开发新的应用。关键是它们与量子纠缠态具有显著的相似性,这是由于空间和偏振自由度(DoF)之间的不可分离性。因此,对生成方法和表征技术多样化的需求急剧增加。在这里,我们提出了一个全面的教程,使用DMD的矢量模式的生成和表征,提供详细的技术实施,充分利用数字微镜器件(DMD)的无与伦比的优势,如其高刷新率和偏振独立性。我们首先简要描述DMD的工作原理,然后详细解释塑造任意矢量模式的一些方法。最后,我们描述了一些针对矢量光束的实时表征技术。本教程强调了DMD作为复杂矢量光场生成和表征的替代工具的价值,在各种应用中具有重要意义。

英文摘要:

Complex vector light modes with a spatial variant polarization distribution have become topical of late, enabling the development of novel applications in numerous research fields. Key to this is the remarkable similarities they hold with quantum entangled states, which arises from the non-separability between the spatial and polarisation degrees of freedom (DoF). As such, the demand for diversification of generation methods and characterization techniques have increased dramatically. Here we put forward a comprehensive tutorial about the use of DMDs in the generation and characterization of vector modes, providing details on the implementation of techniques that fully exploits the unsurpassed advantage of Digital Micromirrors Devices (DMDs), such as their high refresh rates and polarisation independence. We start by briefly describing the operating principles of DMD and follow with a thorough explanation of some of the methods to shape arbitrary vector modes. Finally, we describe some techniques aiming at the real-time characterization of vector beams. This tutorial highlights the value of DMDs as an alternative tool for the generation and characterization of complex vector light fields, of great relevance in a wide variety of applications.
