NON-LINEAR PROCESSES ON FORMATION AND INTERACTION OF FEMTOSECOND OPTIC SOLITONS

The aim is to develop the theory on the formation, propagation and interaction of the optic solitons in the fibrous light guides, to investigate the possibility for generation of the femtosecond soliton-similar pulses in the media with different spectral properties. The possibility of the transmission in the dustances exceeding sufficiently the dispersion spreading lenght of the stable pulse sequences in the positive dispersion mode of the group rate at support by the antiphase solution pair has been shown theoretically. It has been determined by the methods of numerical modelling that the tunneling of the femtosecond soliton spectrum through the heterogeneities of the group rate dispersion dependence upon the type frequency of the potential barriers and holes is possible in the spectral-heterogeneous media. A possibility to increase the efficiency of the spectral-limited amplification at the expense of the forced combination scattering suppression - self-transformation in the spectral-heterogeous media has been shown. Usage field: fibre and integrated optics, optic control systems.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
