Résumé :

A propagation of train of chirped vector solitons in birefringent optical fibers with variable coefficients is studied numerically using the compact split step Padé scheme (CSSPS). A negative chirp makes the managed chirped vector soliton broadening, while; a positive chirp leads to a soliton compression. The effect of the chirp on the vector soliton temporal width of an amplification system (σ> 0) is greater than that in a loss system (σ< 0). The evolution of train of managed vector solitons is submitted not only to the effect of the chirp, but also to the interaction between the adjacent vector solitons.
