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

Figure 2

Experimental results of self-trapping of SCVs (top) and DCVs (bottom) in a defocusing photonic lattice. (a) Interferograms showing the phase of the input vortex beams, (b) intensity patterns of self-trapped vortex beams at lattice output, (c, d) interferograms between (b) and a tilted plane wave (c) and an on-axis Gaussian beam (d), respectively, and (e) the -space spectra of (b) where the dash squares mark the first Brillouin zone of the square lattice. (a, c) are zoomed in with respect to (b, d) for better visualization.
