✦ Synopsis

The gain and noise characteristics of ¨-groo¨e wa¨eguide amplifiers with high Er concentration are predicted using finite-element simulation. A four-le¨el model which includes the effects of up-con¨ersion and cross relaxation was used. The simulations predict that a net gain of 7.2 dB is possible with 100 mW of pump power in a 4 cm amplifier.

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
