Abstract: In this paper, the optical wave propagation in lossy waveguides is described by the Helmholtz equation with the complex refractive-index, and the chebyshev pseudospectral method is used to discretize the transverse operator of the equation. Meanwhile, an operator marching method, a one-way re-formulation based on the Dirichlet-to-Neumann (DtN) map, is improved to solve the equation. Numerical examples show that our treatment is more efficient.
This submission is an expanded paper of author's prior work, and its main content is the research of optical wave propagation in lossy waveguides by solving a 2D Helmholtz equation with the Chebyshev pseudospectral method. The structure of this paper is great, and its derivations are rigorous. The final numerical results show that the proposed method is valuable to improve the precision.
