Anisotropy-controlled topological stability of discrete vortex solitons in optically induced photonic lattices

Terhalle, Bernd; Göries, Dennis; Richter, Tobias; Rose, Patrick; Desyatnikov, Anton S; Kaiser, Friedemann; Denz, Cornelia

Description

We realize an experimental control over the topological stability of three-lobe discrete vortex solitons by modifying the symmetry of a hexagonal photonic lattice optically induced in a photorefractive crystal. By continuously deforming the lattice wave in one transverse direction, we manipulate the coupling between lattice sites and induce or inhibit the reversal of soliton vorticity.
