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.

Key words: integrated optics, Erbium-doped glass optical waveguide, optical amplifier, ADI-FDTD
