Observation of topological transformations of optical vortices in two-dimensional photonic lattices

Bezryadina, Anna; Neshev, Dragomir; Desyatnikov, Anton S; Young, Jack; Chen, Zhigang; Kivshar, Yuri


We study interaction of a discrete vortex with a supporting photonic lattice and analyze how the combined action of the lattice periodicity and the medium nonlinearity can modify the vortex structure. In particular, we describe theoretically and observe in experiment, for the first time to our knowledge, the nontrivial topological transformations of the discrete vortex including the flipping of vortex charge and inversion of its orbital angular momentum. We also demonstrate the...[Show more]
