Abstract: The optical field distribution of Erbium-doped glass planar waveguide is calculated first by the Finite-Differences Time-Domain based on Alternating-Direction Implicit Method (ADI-FDTD).The principal advantage of this method is that it can simulate the characteristics of the optical field in the waveguide.Its algorithm is simple and the results are unconditionally stable.
