We propose a scheme for the coupler-free excitation of surface polaritonic solitons and breathers in a planar plasmonic waveguide structure comprising a transparent layer, a metal layer, and a layer of a three-level lambda-type atomic medium. In the proposed system, an enhanced Kerr nonlinearity is achieved via electromagnetically induced transparency (EIT) in the bottom atomic medium, which can be controlled through proper modulation of the frequency detunings and Rabi frequencies of the…

Localized gap modes of coherently trapped atoms in an optical lattice.

TLDR
A nonlinear equation governing the spatial-temporal evolution of the probe-field envelope is derived and the formation and properties of optical localized gap modes of two kinds, such as the fundamental gap solitons and dipole gap modes are uncovered.

Giant Kerr nonlinearity and low-power gigahertz solitons via plasmon-induced transparency

TLDR
It is shown that the PIT in a new type of metamaterial constructed by an array of unit cell consisting of a cut-wire and a pair of varactor-loaded split-ring resonators can not only mimic the electromagnetically induced transparency in coherent three-level atomic systems, but also exhibit a crossover from PIT to Autler-Townes splitting.

Surface plasmon polaritons (SPPs) are electromagnetic excitations existing at the interface between a metal and a dielectric material. Remarkable progress has been made in the field of SPPs in recent

Plasmon induced transparency effect through alternately coupled resonators in terahertz metamaterial.

TLDR
The PIT effect is explored in a metamaterial comprising of a cross like structure and four C-shaped resonators, and it is observed that such a structure exhibits equally strong PIT effects for both the incident polarizations, indicating a polarization independent response to the incident terahertz radiation.
