利用一阶波动方程的一种改进形式，研究了无缓变包络近似的非线性脉冲在光子晶体光纤中的传输。超连续谱的产生是由于高阶孤子分裂为红移的基孤子和蓝移的非孤子辐射而产生的一种新的光谱展宽机制。与实验观测结果吻合较好，并对亚周期脉冲压缩进行了研究。
The nonlinear pulse propagation in photonic crystal fibers without slowly varying envelope approximation is studied using an improved variant of first-order wave equation. Supercontinuum generation is shown to be caused by a novel mechanism of spectral broadening through fission of higher-order solitons into redshifted fundamental solitons and blueshifted nonsolitonic radiation. Good agreement with experimental observations is found, and subcycle pulse compression is studied.
