    • Observation of localized modes at phase slips in two-dimensional photonic lattices 
      Szameit, Alexander; Molina Gálvez, Mario; Heinrich, Matthias; Dreisow, Felix; Keil, Robert; Nolte, Stefan; Kivshar, Yuri S. (OPTICAL SOC AMER, 2010-08-15)
      We study experimentally light localization at phase-slip waveguides and at the intersection of phase-slips in a two-dimensional (2D) square photonic lattice. Such system allows to observe a variety of effects, including ...
    • Spatially localized modes in two-dimensional chirped photonic lattices 
      Molina Gálvez, Mario; Kartashov, Yaroslav V.; Torner, Lluis; Kivshar, Yuri S. (AMER PHYSICAL SOC, 2008-05)
      We numerically study both linear and nonlinear surface modes in semi-infinite chirped two-dimensional photonic lattices in the framework of an effective discrete nonlinear model. We demonstrate that the lattice chirp can ...
    • Surface solitons in quasiperiodic nonlinear photonic lattices 
      Martínez, Alejandro J.; Molina Gálvez, Mario (AMER PHYSICAL SOC, 2012-01-04)
      We study discrete surface solitons in semi-infinite, one-dimensional, nonlinear (Kerr), quasiperiodic waveguide arrays of the Fibonacci and Aubry-Andre types, and explore different families of localized surface modes, as ...
    • Vortex solitons of the discrete Ginzburg-Landau equation 
      Mejía Cortés, Cristian; Soto Crespo, J. M.; Vicencio Poblete, Rodrigo; Molina Gálvez, Mario (AMER PHYSICAL SOC, 2011-04-29)
      We have found several families of vortex soliton solutions in two-dimensional discrete dissipative systems governed by the cubic-quintic complex Ginzburg-Landau equation. There are symmetric and asymmetric solutions, and ...
