Discrete Self-Trapping vs Defocusing in Nonlinear Waveguide Arrays

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


We predict a sharp crossover from self-defocusing to discrete localization in photonic lattices with defocusing nonlinearity for increasing index contrast. We demonstrate experimentally discrete self-trapping of light by single site excitation in LiNbO3 waveguide arrays.
