Elimination of Split and Deformation for Optical Soliton in TIRPCF Using CSDDMS

摘要

The concept of the concentrated slowly decreasing dispersion management soliton(CSDDMS) is explained, and the nonlinear Shrdinger equation(NSE) of the soliton propagation in the total internal reflective photonic crystal fiber(TIRPCF) under the multi-photon nonlinear Compton scattering is given. Through solving of this equation using the Fourier transform by step, it is found that under certain conditions, the soliton couple becomes into the quasi-solitons, whose amplitudes and widths are slowly and periodically changed, but there is any collision. A new method to eliminate the split and deformation of the optical soliton in the TIRPCF using the CSDDMS is proposed.
