摘　　要：解析求解了双包层椭圆光纤中的波动方程，得到了模式场精确解及模式特征方程。对基模的特征方程进行了数值计算，给出了不同椭圆比下的归一化双折射和模间色散随归一化频率的变化关系曲线。The analytical solutions of electromagnetic wave equations for double clad elliptical optical waveguide have been studied. The mode field distribution and the mode characteristic equations are obtained. The numerical solution for charactistic equations of fundamental modes are derived. The normalized birefringence and modal dispersion as functions of normalized frequency for different aspect ratios are presented and compared with Guassian approximation.
