Abstract
We analyze phase matching in metal-dielectric nonlinear structures which support highly localized plasmen polaritou modes. We reveal that quadratic phase matching between the plasmen modes of different symmetries becomes possible in planar waveguide geometries. We discuss the example of a nonlinear LiNbO 3 waveguide sandwiched between two silver plates, and demonstrate that second-harmonic generation can be achieved for interacting plasmonic modes.
