Abstract

The properties of pulse propagation in a nonlinear fiber including linear damped term added in the usual nonlinear Schr\"odinger equation is analyzed analytically. We apply variational modified approach based on the lagrangian that describe the dynamic of system and with a trial function we obtain a solution which is more accuracy when compared with a pertubative solution. As a result, the problem of pulse propagation in a fiber with loss can be described in good agreement with exact results.
