pplication of FDTD-overlapping Integral Method in Simulation of Waveguide Amplifier
A novel algorithm, calling FDTD-based overlapping integral-RK method, is pr posed to analyze Er-Yb co-doped phosphate glass IR waveguide amplifiers. This new method derived from the combination of Finite-difference Time-Domain (FDTD), overlapping integ and RK method. First the normalized eigen-fields of signal and pump lights in Er-Yb co-dop phosphate glass waveguide are calculated by FDTD algorithm, and then the overlapping integr between light fields and the distribution of Er3+(Yb3+) concentrations are obtained, finally t distributions of poffers of signal and pump along waveguide are calculated by RK method. Ga performance of IR waveguide amplifiers is obtained from calculated signal power. Comparis of the simulation result with an experiment is given, it demonstrates that this new algorith is valid and shows good agreement with experimental results. Abstract should summarize t approach and the articles major contributions, emphasizing the importance and significance the results.
