Discrete surface solitons in two-dimensional anisotropic photonic lattices
arXiv:nlin/0610049 · doi:10.1016/j.physleta.2006.12.035
Abstract
We study nonlinear surface modes in two-dimensional {\em anisotropic} periodic photonic lattices and demonstrate that, in a sharp contrast to one-dimensional discrete surface solitons, the mode threshold power is lower at the surface, and two-dimensional discrete solitons can be generated easier near the lattice corners and edges. We analyze the crossover between effectively one- and two-dimensional regimes of the surface-mediated beam localization in the lattice.
