Abstract :
We report on the first observation of surface gap solitons, a nonlinear optical analog of localized surface Tamm states in periodic electronic potentials. We demonstrate strong beam self-trapping in the form of staggered surface modes at the interface between uniform and periodic dielectric media with defocusing nonlinear response.
