摘要
涡旋光束具有螺旋波前、携带相位奇点和轨道角动量等物理特性,在粒子操控、量子信息、超分辨成像、光通信等领域具有重要的应用,并已成为学术界的研究热点。得益于相干光学理论的快速发展,将相干性作为新的自由度引入涡旋光束中,提出新型涡旋光束即部分相干涡旋光束。相较于完全相干涡旋光束,部分相干涡旋光束具有独特的物理内涵和光学特性,尤其是对其相干性和拓扑荷的联合调控会引发一系列奇特的新物理效应(如相干奇点、光束整形、偏振态转换、自修复等)。回顾了部分相干涡旋光束的基本理论及发展历程,着重对部分相干涡旋光束的理论模型、传输特性、实验产生、实验测量和应用基础研究进行了阐述。
Vortex beams have physical properties such as spiral wave-fronts, phase singularities, and orbital angular momentum, which have important applications in particle manipulation, quantum information, super-resolution imaging, optical communication and so on, and become the spotlight of optical researches. Owing to the rapid development of the optical coherence theory, the researchers have introduced the coherence as a new degree of freedom into the vortex beams and proposed the partially coherent vortex beams as an extension of coherent vortex beams. Such partially coherent vortex beams, compared with the fully coherent ones, have their unique physical meanings and optical properties. Particularly, some new peculiar effects(such as coherence singularities, beam shaping, polarization switches, and self-healing) emerge when the coherence and the topological charges of the partially coherent vortex beams are modulated. Here, an overview on the fundamental theory and the development history of the partially coherent vortex beams is presented. The theoretical models, the propagation characteristics,the experimental generations and measurements, as well as the applications are introduced with the combination of our recent research works.
