Surface solitons in two-dimensional quadratic photonic lattices
arXiv:0903.2858 · doi:10.1364/JOSAB.26.001545
Abstract
We study two-color surface solitons in two-dimensional photonic lattices with quadratic nonlinear response. We demonstrate that such parametrically coupled optical localized modes can exist in the corners or at the edges of a square photonic lattice, and we analyze the impact of the phase mismatch on their properties, stability, and the threshold power for their generation.
