“…This two-component pulse has a very special form and they are met in different fields of research: in optics, acoustics, plasma physics, hydrodynamics, particle physics, and etc. In the optical and acoustic self-induced transparency, such wave is called the vector 0π pulse [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Using the generalized perturbation reduction method the scalar nonlinear Schrödinger equation is transformed to the coupled nonlinear Schrödinger equations for auxiliary functions. A solution in the form of a two-component vector nonlinear pulse is obtained. The components of the pulse oscillate with the sum and difference of the frequencies and wave numbers. Explicit analytical expressions for the shape and parameters of the two-component nonlinear pulse are presented.

“…SIT for SQDs has been considered for plane waves [20,21] and waveguide modes [22] as well as for SPPs in conventional media [23], in isotropic LHMs [24,25], and in indefinite LHMs [15]. The propagation of SPPs in uniaxial anisotropic LHMs with simultaneously negative principal components of the permittivity and permeability tensors is absolutely different from the earlier investigated cases.…”

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.
