Nonlinear Surface Plasmon Polaritons at the Interfaces Between Isotropic Media and Anisotropic Left-Handed Materials

ABSTRACT

Linear and nonlinear surface plasmon polaritons propagating along the interfaces between isotropic media and uniaxially anisotropic left-handed materials are investigated. A transition layer sandwiched between the connected media is described using a model of a two-dimensional gas of semiconductor quantum dots. The conditions of the existence of surface TM-modes when the components of the permittivity and permeability tensors of the anisotropic left-handed materials are simultaneously negative are determined. Explicit analytical expressions for a surface optical twodimensional soliton of self-induced transparency in the presence of single and biexciton transitions are given. Numerical simulations for surface solitons are given for different layered systems. It is shown that the total energy flow of the surface solitons depends on the parameters of the quantum dots and the connected media.
