The physical meaning for each of the term in the coupling coefficient is stated . in particular , we advance firstly ( as far as our knowledge ) , that the birefringence can cause additional coupling for the directional coupler . then , taking the ti - diffused linbo3 directional coupler and the ti - diffused linbo3 with gradient refractive index for examples , we make the numerical simulation for the coupling coefficient or the propagation constant , which prove that the birefringence has played a crucial effect on the propagation constant and the coupling between the modes that we can not neglect
第二，我们推导出了弱导近似下各向异性光波导在任意微扰下的非正交耦合模理论，得到了物理意义鲜明的耦合波方程和耦合系数表达式，指明了耦合系数所包含的四项各自的物理意义及在不同条件下的取舍，首次提出在方向耦合器中双折射将引起附加的耦合，并以钛扩散铌酸锂方向耦合器和折射率渐变分布的钛扩散铌酸锂矩形波导为例对耦合系数进行了数值模拟，充分体现了双折射项对传播常数的影响。
