集成光学中的电磁波导是一种在一个空间方向上平移不变的传播结构，其横截面是分层介质的局部扰动。本文提出了一种在弱导引假设下计算此类器件导模的新方法。该方法结合了多种分析技术，考虑了传播介质的无界和分层特性，使得数值计算可以简化为摄动的邻域。
Electromagnetic waveguides in integrated optics are propagation structures which are invariant under translation in one space direction and whose cross section is a local perturbation of a stratified medium. In this paper, we propose a new method for computing the guided modes of such devices under the weak guiding assumption. The method results from a combination of analytical techniques which take into account the unbounded and stratified character of the propagation medium so that numerical computations can be reduced to a neighborhood of the perturbation.
