Paper Abstract

An experimental and numerical investigation of active waveguides realized on lithium niobate crystals using erbium as doping element is presented. A systematic study of Er diffusion in LiNbCO3 is performed with secondary ion-mass spectrometry to determine surface concentration, penetration depth and diffusion coefficient of erbium as function of various process parameters. A software package is implemented to simulate the propagation of electromagnetic field in active waveguides using an Active Vectorial Beam Propagation Method, which permits to calculate the field evolution along the propagation axis. A comparative study of signal gain evolution, optimal device length and threshold pump power as function of erbium depth profile obtained by various doping methods is presented.
