同心矢量完美涡旋模式的特性
|
摘要
完美涡旋光场模式的单一性难以满足其在多种领域的应用需求。为解决该问题,提出了一种同心矢量完美涡旋模式,其光强分布为一族同心的矢量完美涡旋,各环矢量完美涡旋的性质得到了验证。研究发现,每个完美涡旋的光环大小、偏振阶数等特征参数相互独立。对同心矢量完美涡旋模式光环叠加的实验表明,与标量完美涡旋光束叠加不同,矢量叠加产生的子涡旋会在特定位置消失,原因是两光环在该位置偏振正交。该研究极大地丰富了完美涡旋的模式分布,拓宽了完美涡旋在微操纵、光通信等领域的潜在应用。
A perfect vortex beam has only a single simple mode, which restricts its applications in many fields. To overcome this drawback, a concentric vectorial perfect vortex mode is proposed, whose intensity distribution presents a group of concentric vectorial perfect vortices. In addition, the property of each vectorial perfect vortex is tested. The research results show that the characteristic parameters of each vectorial perfect vortex, such as radius and polarization order, are independent on each other. Furthermore, the superposition property of intensity rings of concentric vectorial perfect vortex mode is studied. Different from the scalar superposition, the sub-vortices generated by the vectorial superposition vanish at some specific locations as a result of polarization orthogonality for these rings at these locations. This work vastly enriches the mode distributions of a perfect vortex and broadens its potential applications in the fields of micromanipulation, optical communication and so on.
