Websuch a robust topological dislocation is an optical vortex [32]. Vortices are ubiquitous entities in nature, thus their study is relevant to many areas of physics. In optics, they occur as a screw phase-dislocation nested around a point where the field is undefined, thus the light intensity must vanish. Since the WebAn optical vortex(also known as a photonic quantum vortex, screw dislocationor phase singularity) is a zero of an optical field; a point of zero intensity. The term is also used to describe a beam of light that has such a zero in it. The study of these phenomena is known as singular optics. Explanation[edit]
