Title: Efficient stationary model for erbium-doped optical amplifiers: Numerical and experimental comparisons
Author: Lopez-Barbero, AP
Hernandez-Figueroa, HE
Abstract: An efficient model for erbium-doped optical amplifiers is presented in this paper. This model, based on an iterative finite-element stationary (modal analysis) scheme in conjunction with a suitable multilevel rate equations system, permits a direct computation of the complex propagation constant beta. In addition, the use of absorption/emission cross-section parameters permits the computation of the gain, related to Im{beta}, and induced nonlinearities, related to Re{beta}, over a wideband spectrum (1.40-1.65 mu m). Since up-conversion and cross-relaxation effects are taken into account, the model is also able to analyze highly doped waveguides. Comparisons with other approach and experimental data validate this model. (C) 1999 John Wiley & Sons, Inc.
