从单个数字全息图产生多个矢量光束

Generation of multiple vector beams from a single digital hologram

Carmelo Rosales-Guzmán, Nkosiphile Bhebhe, Andrew Forbes

摘要:

复杂的矢量光场,经典的纠缠在偏振和相位,已成为无处不在的各种研究领域。这引发了各种发电技术的演示。特别相关的是那些基于计算机控制的设备,因为它们具有很大的灵活性。更具体地,空间光调制器已经证明,可以生成具有各种空间轮廓和偏振分布的几乎任何矢量光束。至关重要的是,这些技术都没有被证明能够同时产生多个矢量光束。在这里,我们提出了一种新的技术,利用光学叠加原理,使许多矢量光束使用一个单一的数字全息图同时产生。作为原理验证,我们演示了在单个SLM上同时产生20个具有不同偏振分布和空间形状的矢量涡旋光束,每个矢量涡旋光束都具有自己的空间形状和偏振分布。

英文摘要:

Complex vector light fields, classically entangled in polarization and phase, have become ubiquitous in a wide variety of research fields. This has triggered the demonstration of a wide variety of generation techniques. Of particular relevance are those based on computer-controlled devices due to their great flexibility. More specifically, spatial light modulators have demonstrated that almost any vector beam, with various spatial profiles and polarization distributions can be generated. Crucially, none of these techniques has proven capable to generate multiple vector beams simultaneously. Here, we put forward a novel technique that exploits the superposition principle in optics to enable the simultaneous generation of many vector beams using a single digital hologram. As proof-of-principle, we demonstrated the simultaneous generation of twenty vector vortex beams with various polarization distributions and spatial shapes on a single SLM, each of which with their own spatial shape and polarization distribution.
