title: Surface plasmonic lattice solitons.
abstract: We reveal the existence of the surface plasmonic lattice solitons (surface PLSs) at the boundary of a semi-infinite metallic-dielectric periodic nanostructure. We find that the truncation of the periodic structure imposes a threshold power for the existence of surface PLSs, and significantly enhances the modal localization. The propagation and excitation of surface PLSs as well as their potential application in the all-optical subwavelength switching are also demonstrated.
