    • Anderson cross-localization 

      Stützer, Simon; Kartashov, Yaroslav V.; Vysloukh, Victor A.; Tünnermann, A.; Nolte, Stefan; Lewenstein, Maciej; Torner Sabata, Lluís; Szameit, Alexander (2012)
      Article
      Restricted access - publisher's policy
      We report Anderson localization in two-dimensional optical waveguide arrays with disorder in waveguide separation introduced along one axis of the array, in an uncorrelated fashion for each waveguide row. We show that the ...
    • Observation of the gradual transition from one-dimensional to two-dimensional Anderson localization 

      Naether, U.; Kartashov, Yaroslav; Vysloukh, Victor A.; Nolte, S.; Tünnermann, A.; Torner Sabata, Lluís; Szameit, A. (2012-02-15)
      Article
      Restricted access - publisher's policy
      We study the gradual transition from one-dimensional to two-dimensional Anderson localization upon transformation of the di-mensionality of disordered waveguide arrays. An effective transition from one- to two-dimensional ...
    • Three-dimensional light bullets in arrays of waveguides 

      Minardi, Stefano; Eilenberger, F.; Kartashov, Yaroslav V.; Szameit, Alexander; Röpke, U.; Kobelke, J.; Schuster, K.; Bartelt, H.; Nolte, Stefan; Torner Sabata, Lluís; LEDERER, FALK; Tünnermann, A.; Pertsch, T. (2010-12-20)
      Article
      Restricted access - publisher's policy
      We report the first experimental observation of three-dimensional light bullets, excited by femtosecond pulses in a system featuring quasi-instantaneous cubic nonlinearity and a periodic, transversally modulated refractive ...
    • 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)
      Article
      Restricted access - publisher's policy
      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 ...
