非线性光纤方向耦合器孤子动力特性分析 总被引:2,自引:0,他引:2
利用变分方法,导出了双曲正割型光孤子在非线性光纤耦合器中传输时满足的动力学方程组,分析了该方程组的平衡点性态,讨论了光孤子的开关特性.指出参数|β|<2π.是能实现完全的开关操作的必要条件. 相似文献

1 INTRODUCTION During the study of polynuclear complexes with the aim to investigate the magnetic super-exchange interaction between the adjacent metal ions bridged by a conjugation molecule[1], we have made efforts to prepare complexes bridged by 4, 5-diazafluorene-9-one azine (DAA) and found that the coordination ability of DAA is poor in the acidic solution. In order to probe the reason, DAA has been crystallized from the hydrochloric acid solution and its crystal structure has b… 相似文献

1 INTRODUCTION As 4,5-diazafluoren-9-one (dafone) is structu- rally similar to phenanthroline (phen), dafone has been used as a chelating reagent in preparing metal complexes. Several dafone-chelating complexes, such as Cu(II)-dafone complexes with an e… 相似文献
