Abstract

For our studies of laseractive rare earth ions in dielectric optical waveguides we have implanted Nd and Er ions into x and zcut LiNbO3 single crystals. We show the recrystallization of the host and the rare earth diffusion during annealing. Nd and Er have different solubilities and different diffusion constants in LiNbO3. The solubility is strongly temperature dependent. The diffusion is substitutional fastest parallel to c-axis of the LiNbO3 crystal and characterized by an activation energy of approximately 3. 6 eV.
