Optical vortices: the concept of topological potential and analogies with two-dimensional electrostatics

Anderson M. Amaral, Edilson L. Falcão-Filho, Cid B. de Araújo

We show how the phase profile of a distribution of topological charges (TC) of an optical vortex (OV) can be described by a potential analogous to the Coulomb's potential for a dis…
