Observation of nonlinear surface waves in modulated waveguide arrays. Academic Article uri icon


  • We describe theoretically and study experimentally nonlinear surface waves at the edge of a modulated waveguide array with a surface defect and a self-defocusing nonlinearity. We fabricate such structures in a LiNbO(3) crystal and demonstrate the beam switching to different output waveguides with a change of the light intensity due to nonlinear coupling between the linear surface modes supported by the array.
