本文讨论了非线性对称平板波导中的 TE波的偶模及奇模的传输问题 .平板波导的芯区材料是由 Pockels介质所构成 ,包层与衬底是相同的线性材料 .Pockels介质的介电系数为ε=n2 +α|E|,故问题归结为求解芯区的传输方程 .本文给出了芯区、包层及衬底中光波的解析解以及传播常量β的本征值方程等 In this paper, the problem of even-mode and odd-mode transmission of TE wave in a nonlinear symmetric slab waveguide is discussed. The core material of a slab waveguide is made of Pockels medium and the cladding is the same linear material as the substrate. The electric coefficient is ε = n2 + α | E |, so the problem can be attributed to solving the transport equation of the core region.In this paper, the analytical solutions of the light waves in the core region, the cladding and the substrate and the eigenvalue equations
