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.Keywords: Nanotechnology; Photonics; Defocusing; Dielectric medium; Electronic potentials; Gap solitons; International conferences; Nanoscience and nanotechnology (NST); Non-linear responses; Nonlinear optical (NLO); Photonic lattices; Self trapping (ST); Surface m Nonlinear optics; Nonlinear waveguides; Optical solitons; Periodic media; Surface waves; Tamm states200610.1109/ICONN.2006.3406532015-12-07
