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

Figure 5

Experimental results of vortex self-trapping under single-site surface excitation (top) and four-site surface excitation (bottom). (a) Lattice beam superimposed with the vortex beam, (b) linear and (c) nonlinear output of the vortex beam, where blue dashed line indicates the surface location, (d) zoom-in interferogram of (c) with an inclined plane wave, and (e) -space spectrum of (c). The dashed square in (e) marks the boundary of the first Brillouin zone.
