Experiments on Linear and Nonlinear Localization of Optical Vortices in Optically Induced Photonic Lattices

Figure 3

Simulation results of singly charged (a) and doubly charged (b) vortex beams propagating to a longer distance of 40 mm. Shown are the output transverse ( ) intensity pattern (left), its interferogram with a tilted plane wave (middle), and its -space spectrum (right) in both (a) and (b). Notice that the vortex singularity maintains in (a) but disappears in (b).
