| 摘 要： | 文中研究了全光纤结构双波长泵浦光子晶体光纤超连续谱的形成过程和基本理论。在分析了全光纤结构双波长泵浦实验方案的理论模型的基础上，依据模型采用自适应分步傅里叶法求解广义非线性薛定谔方程，相继仿真实现了双波长泵浦源的建立以及超连续谱的形成。仿真结果与文献的实验观察相吻合。由仿真结果分析表明:正是由于交叉相位调制主导下孤子自频移和孤子诱捕效应的共同作用，促使超连续谱向短波方向延伸至可见光波段，为双波长泵浦产生超连续谱光源提供理论支持。

| Abstract: | Dual-wavelength-pumped supercontiuum generation in an all-fiber device has been theoretically investigated. Firstly, a theoretical model of dual-wavelength-pumped experimental scheme in an all-fiber device was given. Secondly, by solving the generalized nonlinear Schrdinger equation with the adaptive split-step Fourier method, formation of dual-wavelength pump source and supercontinuum generation one after another were realized. The simulation results agree with the experimental observations very well and reveal that the conjugate action of soliton self-frequency shift and soliton trapping through cross-phase modulation can effectively extend the spectral range to the visible wave band. The research can provide theoretical supports in the realization and construction of dual-wavelength-pumped supercontinuum all-fiber device. |
