Abstract

In this paper, a numerical analysis to model the amplification of nonlinear surface plasmon polaritons (SPPs) propagating along a metal active dielectric interface is presented. Nonlinearity of the medium with gain is considered through the full saturation susceptibility parameter of a two-level model. Above the linear threshold of the gain and loss balance, the nonlinear performance of the amplified SPPs is verified, which agrees well with the experimental results reported in the literature. An important feature of the proposed method is to predict an abrupt increase in output intensity due to amplified spontaneous emission.
