    • Anderson localization in a periodic photonic lattice with a disordered boundary 
      Naether, U.; Meyer, J. M.; Stützer, S.; Tünnermann, A.; Nolte, S.; Molina Gálvez, Mario; Szameit, A. (OPTICAL SOC AMER, 2012-02-15)
      We investigate experimentally the light evolution inside a two-dimensional finite periodic array of weakly coupled optical waveguides with a disordered boundary. For a completely localized initial condition away from the ...
    • Experimental observation of superdiffusive transport in random dimer lattices 
      Naether, U.; Stützer, S.; Vicencio Poblete, Rodrigo; Molina Gálvez, Mario; Tünnermann, A.; Nolte, S.; Kottos, T.; Christodoulides, D.N.; Szameit, A. (IOP Publishing Ltd and Deutsche Physikalische Gesellschaft, 2013)
      We experimentally observe anomalous wavepacket evolution in a realization of a one-dimensional finite binary Anderson model in the presence of short-range correlations. To this end, we employ weakly-coupled optical waveguides ...
    • Observation of the gradual transition from one-dimensional to two-dimensional Anderson localization 
      Naether, U.; Kartashov, Y. V.; Vysloukh, V. A.; Nolte, S.; Tünnermann, A.; Torner, L.; Szameit, A. (OPTICAL SOC AMER, 2012-02-15)
      We study the gradual transition from one-dimensional (1D) to two-dimensional (2D) Anderson localization upon transformation of the dimensionality of disordered waveguide arrays. An effective transition from a 1D to a 2D ...
    • Pseudo-two-dimensional random dimer lattices 
      Naether, U.; Mejía Cortés, Cristian; Vicencio Poblete, Rodrigo (Elsevier, 2015)
      We study the long-time wave transport in correlated and uncorrelated disordered 2D arrays. When a separation of dimensions is applied to the model, we find that the previously predicted 1D random dimer phenomenology also ...
