本文提出了一种精确分析各向异性分层介质平板波导的新方法，该波导可能具有光损耗或光增益。将波导本征值方程转换为便于数值处理的形式，可以有效地计算波导色散关系。该方法保证了所有约束模态都能被发现，并能处理退化和近退化模态。介质和半导体波导进行了分析，以及波导，包括金属层。梯度折射率结构的分析，细分的梯度配置文件成一个多步骤的配置文件。
A new method is presented for exact analysis of planar waveguides formed by stratified anisotropic media with possible optical loss or gain. Putting the waveguide eigenvalue equation into a form that is convenient for numerical treatment permits efficient calculation of the waveguide dispersion relation. The method guarantees that all confined modes are found, and it handles degenerated and nearly degenerated modes. Dielectric and semiconductor waveguides are analyzed, as well as waveguides that include metallic layers. Graded-index structures are analyzed by subdivision of the graded profile into a multiple-step profile.
