The propagation of ultrashort chirped hyperbolic secant shape and rectangular pulses in a nonlinear lossless fiber is considered. Nonlinear Schrodinger Equation is solved numerically for complex initial conditions using the Split-Step Fourier and the Beam Propagation Methods. It is demonstrated that a hyperbolic secant shape pulse is less sensitive to destructive influence of the initial chirp than a rectangular pulse.
