    • 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 chirped photonic lattices 

      Molina Gálvez, Mario; Kartashov, Yaroslav V.; Torner, Lluis; Kivshar, Yuri S. (2007)
      We study surface modes at the edge of a semi-infinite chirped photonic lattice in the framework of an effective discrete nonlinear model. We demonstrate that the lattice chirp can change dramatically the conditions for the ...
