Effect of fiber chromatic dispersion on incident super-Gaussian pulse transmission in single-mode fibers

Taking into account the chromatic dispersion, the evolution of an incident super-Gaussian pulse during propagation in single-mode fibers has been investigated numerically. The results show that for an incident super-Gaussian pulse, with steep leading and trailing edges, its shape undergoes a variation from near-rectangular to two-peak and, finally, to single-peak. Meanwhile its peak intensity increases at first then, after passing a maximum, finally decreases monotonically.
