Abstract
Surface polaritons (SP) are electromagnetic waves that propagate near the interface of two media with electric field amplitudes strongly decaying with distance from the interface. The two media could be left-handed with both the electric permittivity and magnetic permeability being negative. These media give us new possibilities of slow light control [1,2]. Here we propose to control SP mode propagation in left-handed materials using SP-SP induced transparency. In the proposed scheme, the spatially confined SP interacts with three level lambda type atoms near the surface. An expression for the complex absorption coefficient in the presence of additional control SP mode is derived. We demonstrate a new specific spectral behavior of the probe SP mode propagation that are determined by the spatial properties of interaction between the SP modes and three level atoms. Optimal conditions for the SP mode control will be discussed.
