Abstract

We propose an efficient numerical method, based on the unusual molecular-dynamical algorithm, for the mode analysis in optical waveguides. This method can properly take into account the vector nature of light waves. The vector-wave analysis is treated as the eigenvalue problem of large-scale nonsymmetric matrices with real eigenvalues. The efficiency of the method is demonstrated by calculating dispersion relations of a rectangular dielectric waveguide and supermodes in a nonsymmetric rib waveguide directional coupler. The advantages lie in its being easily vectorized and parallelized for implementation on array-processing modern supercomputers.
