Abstract :
High-concentration Er3+/Yb3+ codoped glass waveguide amplifiers are analyzed by means of a finite-element-based code. Efficient Yb3+ to Er3+ energy transfer is shown to be a useful mechanism to reduce performance degradation due to Er3+ ion-ion interactions. Numerical calculations based on realistic waveguide parameters demonstrate the possibility of achieving high gain with a short device length
