Study of Cylindrical Vector beams and its applications

Abstract

In this study, the intrinsic properties of the CV beams are fully investigated based on vector diffraction theory. A clear and complete toolkit to design binary lens for focusing manipulation has been developed in this thesis. Firstly, based on the intrinsic properties of CV beams, a systematic and efficient way to generate various optical patterns is established. Secondly, the vectorial Rayleigh-Sommefeld method is derived and demonstrated to design and optimize flat lens for generation of spot or needle with full control of polarization and sidebands. Rigorous classification and explicit definition to distinguish diffraction limit, super-resolution, and super-oscillatory focusing are also established. Finally, a novel method is proposed to design arbitrary super-oscillatory lens, which empowers the construction of a customized super-oscillatory pattern with significantly enlarged field-of-view possible to be implemented without the traditional optimizing technique.
