The evolution of self-similar parabolic pulses is demonstrated by designing a parabolic index dispersion decreasing fiber amplifier with normal dispersion (ND-DDF amplifier), with inclusion of the variation of nonlinear factor (¿) with distance. The pulse transmission is extensively studied for the proposed ND-DDF in presence of external gain as well as virtual gain induced by its dispersion profile. The output power resembles with a perfect parabolic shape giving rise to self-similar pulses with minimum misfit ¿ 0.003. In view of practical aspects of fabrication we also obtain several equivalent staircase profiles, whose performances are shown to be very close to that of the proposed ND-DDF.
