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

Figure 6

Numerical simulation of single-site (top) and four-site (bottom) surface excitation of a SCV after 4-cm of nonlinear propagation. Shown are (a) vortex output intensity pattern and (b) its corresponding interferogram, and (c) side-view of the vortex propagation to 𝑧=4 cm.
