| Recent developments in complex light optics have brought great interest in mechanisms to control the motion of vortices during propagation, as vórtices present diverse applications such as particle trapping, wave guiding or classical and quantum communications. Nonlinear Bessel Beams (NBB) produced in self-focusing or selfdefocusing Kerr media that also present multiphoton absorption, are shown here to propagate stably without any attenuation and to be able to attract and guide an arbitrary number of vortices. NBBs create an effective attraction basin in their propagation axis by which any number of vortices placed at arbitrary positions in the beam cross section steer towards the center and combine together, forming a new high-order,vortex NBB with total topological charge equal to the sum of the individual charges of the vortices attracted, and whose propagation is extremely robust against perturbations.The fundamental laws that govern the attraction and subsequent mode conversion of the attracting NBB are found to be the preservation of the topological charge and of the inward-directed power current that sustains the stationary propagation. | |
