The propagation and evolution characteristics of ultra-short pulses in a nonlinearity-increasing fiber were studied based on theoretical analysis and numerical calculation. Numerical simulation shows that the propagation in a nonlinearity-increasing fiber is similar with that in a gain-amplification fiber or dispersion fiber, i.e., the propagation and evolution accords with the self-similar evolution. Finally the parabolic pulse with linear chirp can be achieved. The result is useful for pulse compression because the parabolic pulse has linear chirp.
