At high Er3+ doping, electric dipole-dipole interactions between neighboring ions such as energy migration and energy-transfer upconversion (ETU) take place, thereby reducing the population inversion and negatively affecting the gain performance of the amplifier. These effects are investigated by lifetime and gain measurements respectively, in Al2O3:Er3+ waveguides and analyzed the results in the frame of the microscopic model developed by Zubenko et al.
