基于广义非线性薛定谔方程，数值模拟了具有3个零色散波长的光子晶体光纤中孤子的演化过程及其时频特性。结果表明，由于第2个反常色散区的存在，不仅在正常色散区得到了相位匹配的蓝移和红移色散波，还在低频反常色散区得到了高强度的色散波孤子，而且此孤子在高频正常色散区进一步辐射出了蓝移色散波。

Based on the generalized nonlinear Schrdinger equation, the spectral evolution and the time-frequency characteristics of the soliton in photonic crystal fiber with three zero-dispersion wavelengths are numerically simulated. The results show that not only both blue- and red-shifted dispersive waves are generated in the two normal dispersion regions of the photonic crystal fiber, which is in good agreement with the phase-matching condition, but also high-intensity dispersive wave-soliton is generated in the low-frequency anomalous dispersion region due to the existence of the second anomalous dispersion region. Furthermore, it is found that in high-frequency normal dispersion region the blue-shifed dispersive wave is emitted by the dispersion wave-soliton.
