| Abstract: | 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. |
