Abstract

Two regimes of diffraction that existed in waveguide arrays were shown. The diffraction was observed to depend upon the input conditions. At higher powers, such diffraction lead to self-focusing and soliton formation through the nonlinear Kerr effect. A change in the input conditions resulted in nonlinear defocusing and anomalous diffraction.
