    We show that the geometrically induced potential existing in undulated slab waveguides dramatically affects the properties of solitons. In particular, whereas solitons residing in the potential maxima do not feature power ...
  • Wave localization at the boundary of disordered photonic lattices 

    Szameit, Alexander; Kartashov, Yaroslav V.; Zeil, P.; Dreisow, Felix; Heinrich, Matthias; Keil, R.; Nolte, Stefan; Tünnermann, A.; Vysloukh, Victor A.; Torner Sabata, Lluís (2010-04-15)

    We report on the experimental observation of reduced light-energy transport and disorder-induced localization close to a boundary of a truncated 1D disordered photonic lattice. Our observations uncover that a higher level ...
