单模光纤的三维模场分布目录1 单模光纤.12 单模光纤模场分布近似.13 MATLAB 语言.63、1 主程序.63、2 调用函数.9 3、3 程序运行说明.114 总结.16单模光纤的三维模场分布1单模光纤在工作波长中,只能传输一个传播模式的光纤,通常简称为单模光纤(SMF:Single ModeFiber)。由于光纤的纤芯很细(约 10pm)而且折射率呈阶跃状分布,当归一化频率 V 参数2、4 时,理论上只能形成单模传输。2 单模光纤模场分布光纤中的电磁波可以瞧成时谐场,满足亥姆霍兹方程,与电磁波理论中的做法一样,先求解 z 方向分量,然后再由麦克斯韦方程组求得其她分量。采用柱坐标,z 方向的分量满足亥姆霍兹方程:如果求得 z 方向的分量,其她各横向分量可以用z 分量表示出来。阶跃光纤中的电磁场解及导波模的截止参数式中,A、B 待定常数,Jm:m 阶第一类贝塞尔函数,Km:m 阶第二类变形贝塞尔函数。U=kca W=aca u表示导波模场在纤芯内部的横向分布规律,w 表示它在包层中的横向分布规律,两者结合起来,就可以完整地描述导波模的横向分布规律;就是轴向的相位传播常数,表明导波模的纵向传输特性。文档编码:CT6R3O9S10C7 HS10R3Y6N10C10 ZQ2A6F6N6I3文档编码:CT6R3O9S10C7 HS10R3Y6N10C10
