报道了应用准连续光抽运光子晶体光纤产生超连续谱时的一种现象,并根据调制不稳定和数值解薛定谔方程证明此现象为调制不稳定性.在实验中发现有两个波峰,与中心波长之间的距离分别为27.08 nm和32.72 nm,经过对比和分析数值结算和实验结果非常吻合,说明调制不稳定性在准连续光抽运光子晶体光纤产生超连续谱过程中起着重要的作用.

A phenomenon experimentally emerging in super-continuum generation with a piece of photonic crystal fiber pumped by quasi-continuum wave is reported.According to the numerical simulation which contains using the gain spectrum theory of modulation instability and solving nonlinear Schrdinger equation,it is proved that this phenomenon is generated by modulation instability.After the results of the simulation and the experiment being contrasted and analyzed,it is found that the simulation result including two mentioned methods is in excellent agreement with the experiment result which the wavelength difference between the two spectrum lobes and the central wavelength are 27.08 nm and 32.72 nm respectively.
