Abstract

In this work the optical amplification, in the small signal regime, at 1.5mum in Zn-diffused, proton exchange and reverse proton exchange Er3+-dopedwaveguide amplifiers (EDWAs) based on LiNbO3 under 980 nm excitation has been modelled, including the dominant up-conversion channel activated by this pumping wavelength. The overlapping integrals method has been used to investigate how the spectroscopic changes, induced by the waveguide fabrication technique, affect the optical amplifier performance. In particular, it has been found that either the amplifier threshold and the maximum gain achievable are spectroscopy-dependent and therefore fabrication-dependent.
