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 Webthe wavelength of light. Phase dislocations of the edge type are found in paraxial Gaussian beams [3] as opposed to screw dislocations observed along the axes of Gauss-Laguerre beams [4]. Until now, the vast majority of publications deal with the phase singularities and the associated caustics of mono-chromatic waves.
