Characteristics of Concentric Vectorial Perfect Vortex Mode
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.
