摘要
从光纤耦合器的耦合模方程出发,用奇偶超模对其进行重写,讨论了当输入条件使奇次超模被单独激发时,计算机数值模拟了高阶色散对光纤耦合器稳定性的影响,结果表明:光纤耦合器中在正常和反常色散区均存在不稳定性,并且不稳定性与3阶色散项无关、与4阶色散项有关,给出了增益谱在不同色散区随输入功率的变化关系.
The nonlinear coupled - mode equations are rewritten by odd and even modes. The high - order dispersion on instability have been studied in Fiber Couplers by the computer numerical simulated when odd mode is launched alone. The result shows that there are new types of instability in both the normal and the anomalous - dispersion regimes. Instability is concerned with four - order dispersion and has no relation with three - order dispersion. The gain spectra have been given as function of input power at various kind of dispersion regimes.
