Generation of self-similar parabolic pulse is analytically and numerically demonstrated by designing parabolic index normal dispersion decreasing fiber (NDDF) amplifiers. The pulse transmission is extensively studied for NDDFs in presence of physical gain as well as virtual gain induced by two different dispersion profiles corresponding to two different physical gain coefficients. Here, we introduce...
This work reports the performances of straight and bent normal dispersion decreasing fiber amplifiers (NDDF) to generate self-similar parabolic pulses, including the spatial variation of nonlinear factor. The dispersion tapering along the fiber length of the proposed NDDF is obtained in presence of the external gain. For varying core radii along the fiber length, bend loss being no longer a constant...
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 (gamma) 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...
