Popis: Er3+-doped Al2O3 optical waveguides are analyzed both as single amplifiers and as elements of a 16-channel wavelength division multiplexing transmission system; their performance is compared with that from Er3+-doped SiO2 optical waveguide amplifiers. The amplifier model, based on propagation and population-rate equa tions, includes both uniform and pair-induced up-conversion mechanisms and is solved numerically by combining finite elements and the Runge-Kutta algorithm. The analysis showed that Er3+-doped Al2O3 waveguides exhibit much higher signal gains than Er3+-doped SiO2 waveguides and also that the use of Er3+-doped Al2O3 waveguides reduces the deleterious gain peaking effect, increasing the maximum transmission distance.
