A Numerical Method for Analyzing Multi-Transverse Modes of a Complex Index Waveguide
In order to analyze multi transverse modes of a complex index waveguide, a numerical method named RPS is proposed. It integrates real index numerical method, perturbation method and shooting method rationally. The method is simple, fast and precise, and it avoids searching the solution in the whole complex plane. Numerical example shows that all mode solution can be obtained precisely for either TE mode or TM mode of a complex index waveguide.
