Complex modes in plasmonic nonlinear slot waveguides

Salgueiro, Jose; Kivshar, Yuri


We analyze linear and nonlinear modes of metal-dielectric-metal slot waveguides taking into account the effect of losses at the metallic cladding. First, we study a linear core and then assume it to be nonlinear with a Kerr-type nonlinear response. In the linear case, we summarize the earlier results of the frequency dispersion analysis showing the mode transformation when losses are increasing. For the nonlinear case, after a brief review of the earlier results on the lossless plasmonic slot...[Show more]
