Résumé :

We study in this work, the propagation characteristics of chirped vector solitons in optical fiber systems using the compact split step Padé scheme (CSSPS). This study is done in the case of variable coefficients and in the presence of power law nonlinearity. A negative chirp makes the soliton broadening, while; a positive chirp leads to a soliton compression. The effect of chirp on the soliton temporal width of an amplification system (σ>0) is greater than that in a loss system (σ<0). In the presence of power law nonlinearity, it is clearly noted that, the quintic nonlinearity has a marginal role on the propagation characteristics of the two components of managed chirped vector soliton.
