| Abstract: | The distributing characteristic of the directional coupler is studied.First,the configuration model of the directional coupler is given,and the finite element method is used to solve equation.The optical field of odd mode and even mode is acquired;and the power distribution curve and the change of the couple length along with the center interval of waveguide are acquired. |
