Abstract :
By using the Pade approximation, an efficient method is proposed for the analysis of the optical waveguide discontinuity problem. The eigenvalue problem of the original formulation based on the method-of-lines is replaced by a rational function of the characteristic matrix. The computation time and memory are further reduced by adopting the multistep method.
