Numerical research of flat wideband supercontinuum generation in anomalous dispersion-flattened fibers
反常色散平坦光纤产生平坦宽带超连续谱的数值研究

Supercontinuum generation in anomalous dispersion-flattened fibers through higher-order soliton compression effect is simulated and analyzed in detail. The results show that the second order differential constant of the dispersion parameter, dispersion parameter of the fiber and the pulse width, and peak power of the pump pulse are crucial to flat wideband supercontinuum generation, and the fiber length should also be dissimilarly chosen. It further shows that supercontinuum generation in the fiber mainly results from the interaction of self-phase modulation and group-velocity dispersions, and the higher- order nonlinear effects can be ignored.
