Discrete Self-Trapping vs Defocusing in Nonlinear Waveguide Arrays
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.
