通过随机空间复用高速产生矢量光束

High-speed generation of vector beams through random spatial multiplexing

Xiao-Bo Hu, Si-Yuan Ma, Carmelo Rosales-Guzmán

摘要:

复矢量模式由于其迷人的特性和在各种研究领域中的许多应用而成为最近的热门话题。尽管这种模式可以以各种各样的方式产生,但数字全息术是最灵活和通用的方式之一。沿着这条线,数字微镜器件(DMD)由于其高刷新率而在最近获得普及,这允许以kHz速率生成矢量模式。尽管如此,大多数技术要么受到可以生成的矢量模式的多样性的限制,要么受到它们可以切换的速度的限制。在这里,我们提出了一种基于随机编码的概念的技术,该技术允许以仅受DMD的刷新率限制的速度生成任意矢量波束。我们的技术将在光通信、激光材料加工和光学操纵等研究领域具有重要意义。

英文摘要:

Complex vector modes have become topical of late due to their fascinating properties and the many applications they have found across a broad variety of research fields. Even though such modes can be generated in a wide variety of ways, digital holography stands out as one of the most flexible and versatile. Along this line, Digital Micromirror Devices (DMDs) have gain popularity in recent time due to their high refresh rates, which allows the generation of vector modes at kHz rates. Nonetheless, most techniques are limited either by the diversity of vector modes that can be generated or by the speed at which they can be switched. Here we propose a technique based on the concept of random encoding, which allows the generation of arbitrary vector beams at speeds limited only by the refresh rate of the DMD. Our technique will be of great relevance in research fields such as optical communications, laser material processing and optical manipulation, amongst others.
