The first order weakly - guiding approximation for the eigenvalue equation of hybrid modes in a step - index optical fiber 阶跃光纤中混合模式特征方程的一阶弱导近似
This paper enclose the mode and the density distribution property of the step - index optical fiber after plane wave coupled into it 本文研究均匀平面波本经阶跃光纤的传播特性和输出光强分布特性。
The second part is the mode transition property and the energy occupation of each mode in step - index optical fiber according to the mode solution 结果表明, te _ ( 11 )模是阶跃光纤中传播的基模,并占有总能量的大部分。
Third , the mode solution is obtained using the separation of variables . the last , the mode transition property is discussed when the plane wave transmit in the step - index optical fiber 再次,利用分离变量法推导出平面波在阶跃光纤中传播的模式表达式,讨论了光波在光纤中传播的模式特性。
