Abstract :
A numerical solution based on the pseudospectral scheme is developed for solving the mode characteristics of a nonlinear plasmonic waveguide composed of a thin metal film surrounded by a Kerr-type nonlinear cladding and a linear substrate. The power dispersion curves of the stationary long-range and short-range surface plasmon polaritons are investigated and the field profiles of the two modes are also characterized.
