论文摘要
对实际应用的需求不断提高，迫使对光学涡流（OVS）进行更深入的研究：从产生和测量到OVS的塑造和多个奇异性操纵。本文中，我们提出了一种称为高阶跨相（HOCP）的新型相结构，可以调节OVS来实现多边形形状和奇异性操纵。从理论上讲，我们研究了用HOCP的OV的传播特性。在实验中，我们通过利用HOCP实现了OV的塑形和奇异性操纵。在此基础上，我们讨论了调制后超跨OVS的干扰模式。这项工作提供了一种实现多边形形状和多个奇异性操纵的替代方法，这将促进光学微操作，光学通信和高维量子纠缠中的应用。
Increasing demand for practical applications is forcing deeper research into optical vortices (OVs): from the generation and measurement to shaping and multiple singularities manipulation of OVs. Herein, we propose a new type of phase structure called the high-order cross phase (HOCP) can be employed to modulate OVs to implement both polygonal shaping and singularities manipulation. Theoretically, we investigate the propagation characteristics of OVs with the HOCP. In experiments, we achieve the shaping and singularities manipulation of OVs by utilizing the HOCP. On this basis, we discuss the interference patterns of superposed OVs after the modulation. This work provides an alternative method to achieve both polygonal shaping and multiple singularities manipulation, which will facilitate applications in optical micro-manipulation, optical communication, and high-dimensional quantum entanglement.
