    • Diffractionfree image transmission in kagome photonic lattices 
      Vicencio Poblete, Rodrigo; Mejía Cortés, Cristian (IOP Publishing, 2014)
      We study the propagation of non-diffracting images in kagome photonic lattices. In a weak-coupling regime (discrete approach), the linear spectrum is composed by only three bands, including a completely degenerated and ...
    • 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 ...
    • Mobility of solitons in one-dimensional lattices with the cubic-quintic nonlinearity 
      Mejía Cortés, Cristian; Vicencio Poblete, Rodrigo; Malomed, Boris A. (American Physical Society, 2013)
      We investigate mobility regimes for localized modes in the discrete nonlinear Schr¨odinger (DNLS) equation with the cubic-quintic on-site terms. Using the variational approximation, the largest soliton’s total power admitting ...
    • Observation of a Localized Flat-Band State in a Photonic Lieb Lattice 
      Vicencio Poblete, Rodrigo; Cantillano, Camilo; Morales Inostroza, Luis; Real, Bastián; Mejía Cortés, Cristian; Weimann, Steffen; Szameit, Alexander; Molina Gálvez, Mario (American Physical Society, 2015)
      We demonstrate the first experimental realization of a dispersionless state, in a photonic Lieb lattice formed by an array of optical waveguides. This engineered lattice supports three energy bands, including a perfectly ...
    • 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 ...
