Symmetry breaking in plasmonic waveguides with metal nonlinearities

Davoyan, Arthur R.; Shadrivov, Ilya V.; Kivshar, Yuri


We studied nonlinear effects in plasmonic metal film waveguides and couplers stimulated by third-order optical response due to ponderomotive metal nonlinearities. We analyzed the structure and dispersion of nonlinear plasmonic guided modes and predicted the bifurcations and symmetry breaking of nonlinear modes for the critical powers, depending on the structure dimensions.
