论文摘要
复杂的矢量模式代表了其在空间和极化自由度上不可分割的一般状态，这启发了各种各样的新型应用和现象，例如它们意外的传播行为。例如，他们可以传播描述周期性极化转换，从一个向量梁变为另一个矢量。在这里，我们提出了一种新颖的矢量模式，具有突然自动关注行为的能力。为了实现此类梁，我们编码了圆形通风高斯涡流（CAGV）梁中的空间自由度。我们证明了任意CAGV载体梁的实验生成，并证明了它们的某些特性，例如模式期的旋转。我们预计，这些模式的迷人特性将促使与其自动关注行为和极化分布相关的新应用的发展。
Complex vector modes represent a general state of light nonseparable in their spatial and polarization degrees of freedom, which have inspired a wide variety of novel applications and phenomena, such as their unexpected propagation behaviour. For example, they can propagate describing periodic polarization transitions, changing from one vector beam to another. Here, we put forward a novel class of vector modes with the capability to experience an abruptly autofocusing behaviour. To achieve such beams, we encode the spatial degree of freedom in the Circular Airy Gaussian vortex (CAGV) beams. We demonstrate the experimental generation of arbitrary CAGV vector beams and evince some of their properties, such as a rotation of intermodal phase. We anticipate that the fascinating properties of theses modes will prompt the development of novel applications associated to their autofocusing behaviour and polarization distribution.
