Crossover from self-defocusing to discrete trapping in nonlinear waveguide arrays

Matuszewski, Michal; Rosberg, Christian; Neshev, Dragomir; Mitchell, Arnan; Trippenbach, Marek; Austin, M; Krolikowski, Wieslaw; Sukhorukov, Andrey; Kivshar, Yuri


We predict a sharp crossover from nonlinear self-defocusing to discrete self-trapping of a narrow Gaussian beam with the increase of the refractive index contrast in a periodic photonic lattice. We demonstrate experimentally nonlinear discrete localization of light with defocusing nonlinearity by single site excitation in LiNbO3 waveguide arrays.
