✦ Synopsis


An efficient model for erbium-doped optical amplifiers is presented in this paper. This model, based on an iterati¨e finite-element ( ) stationary modal analysis scheme in conjunction with a suitable multi-le¨el rate equations system, permits a direct computation of the complex propagation constant ␤. In addition, the use of absorptionremission cross-section parameters permits the computation of the gain, related to { } { } Im ␤ , and induced nonlinearities, related to Re ␤ , o¨er a wideband ( ) spectrum 1.40᎐1.65 m . Since up-con¨ersion and cross-relaxation effects are taken into account, the model is also able to analyze highly doped wa¨eguides. Comparisons with other approach and experimental data ¨alidate this model.
