本文报道了利用低强度飞秒脉冲在光子晶体光纤中产生超连续谱的实验研究，为一种新的光谱展宽机制提供了证据。观测结果与我们在不作缓变包络近似的情况下进行的理论计算一致。光谱测量的特殊性及其理论解释表明，光子晶体光纤中白光产生的原因是高阶孤子分裂成红移的基本孤子和蓝移的非孤子辐射。
We report on an experimental study of supercontinuum generation in photonic crystal fibers with low-intensity femtosecond pulses, which provides evidence for a novel spectral broadening mechanism. The observed results agree with our theoretical calculations carried out without making the slowly varying envelope approximation. Peculiarities of the measured spectra and their theoretical explanation demonstrate that the reason for the white-light generation in photonic crystal fibers is fission of higher-order solitons into redshifted fundamental solitons and blueshifted nonsolitonic radiation.
