论文摘要
复杂的光线模式，在空间和极化的自由度上是不可分割的，正在彻底改变各种研究领域。因此，自成立以来，发电技术已经急剧发展，这并不奇怪。目前，使用计算机控制的设备是常见的，其中数字微旋转设备已变得流行。造成这种情况的一些原因是它们的低成本，对极化不敏感和高消除率。因此，在此手稿中，我们提出了一种以其高稳定性为特征的新型技术，该技术是通过常见路径干涉仪实现的。我们首先通过在高阶Poincaré球上生成任意向量模式，其次通过在不同坐标系统中生成向量模式，最后通过同时生成各种矢量模式，从而证明该技术的功能。我们的技术将在诸如光学操纵，光学通信，光学计量学等领域中找到应用。
Complex vector modes of light, non-separable in their spatial and polarisation degrees of freedom, are revolutionising a wide variety of research fields. It is therefore not surprising that the generation techniques have evolved quite dramatically since their inception. At present it is common to use computer-controlled devices, among which digital micromirror devices have become popular. Some of the reason for this are their low-cost, their polarisation-insensitive and their high-refresh rates. As such, in this manuscript we put forward a novel technique characterised by its high stability, which is achieved through a common-path interferometer. We demonstrate the capabilities of this technique experimentally, first by generating arbitrary vector modes on a higher-order Poincaré sphere, secondly, by generating vector modes in different coordinates systems and finally, by generating various vector modes simultaneously. Our technique will find applications in fields such as optical manipulations, optical communications, optical metrology, among others.
