Phase interaction of short vector solitons
An interaction of vector solitons in the frame of coupled third-order nonlinear Schrцdinger equations taking into account third-order linear dispersion, nonlinear dispersion, and cross-phase modulation terms is considered. Phase nature of the solitons' interaction is shown. In particular, dependence of solitons' trajectories on initial distance between solitons is shown. Conditions of reflection and propagation of solitons through each other are obtained.
The interaction of short single-component vector solitons in the frame of the coupled third–order nonlinear Schrodinger equations taking into account third–order linear dispersion, self–stepping, self–stimulated Ramanscattering, cross–stepping and cross–stimulated Raman-scattering terms is considered. Conditions of reflection and propagation of the solitons through each other and also the condition of oscillator interaction (vector breather) are obtained.
Dynamics of short solitons envelope in the frame of the third-order nonlinear Schrodinger equations taking into account stimulated Raman-scattering and inhomogeneous second– and third-order linear dispersion, nonlinear dispersion and cubic nonlinearity is considered. Compensation of the stimulated Raman-scattering effect by the increasing of the second-order linear dispersion is shown. In adiabatic approximation stable soliton’s propagation regime is found. Third-order linear dispersion and nonlinear dispersion inhomogeneity effect to stimulated Raman-scattering compensation is analyzed.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
