Abstract

We investigate the existence of spatial optical solitons supported by an interface between two nonlinear lattices with different saturation parameters. Dipole, quadrupole, and vortex solitons are found in the nonlinear surface lattices. The slight different saturation degree between two sides of the interface leads to a remarkable asymmetry of solitons with higher power. We reveal that multipole and vortex solitons are stable when their power exceeds a threshold value, and stable localized surface nonlinear modes with very high peaks are possible.
