    • 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 bulk and edge transport in photonic Lieb lattices 
      Guzmán Silva, D.; Mejía Cortés, Cristian; Bandres, M. A.; Rechtsman, M C; Weimann, S.; Nolte, S.; Segev, M.; Szameit, A.; Vicencio Poblete, Rodrigo (Deutsche Physikalische Gesellschaft, 2014)
      We analyze the transport of light in the bulk and at the edge of photonic Lieb lattices, whose unique feature is the existence of a flat band representing stationary states in the middle of the band structure that can ...
    • 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 ...
