Abstract: Dielectric waveguides are commonly used in photonic integrated circuits and their accuratemodeling is essential for the development of new, higher performance optical componentsrequired by high-bandwidth communications system. Modal analysis is a critical part ofthe waveguide design process, providing information on the modes that may propagate,such as propagation constants and mode shapes. In brief, by reformulating the Maxwellequation, the problem is deducted to an eigenvalue equation and it can be discretized by afinite difference method. The full-vector waveguide equation is solved by the classicinverse iteration method and the alternating-direction-implicit (ADI). In addition,coordinate stretching technique is employed, which effectively removes the sensitivity ofthe calculated results to the size of the computational domain.
