Notes:
Erbium-doped tellurite glasses show great potential for the fabrication of high-performanceintegrated optical amplifiers and lasers, thanks to their unique properties in terms of bandwidth andrare earth solubility. As a first step towards the development of smart multi-functional integratedoptical circuits, the fabrication of multimode channel waveguides in a sodium-tungsten-telluriteglass, by using nitrogen ions implantation, has been recently demonstrated [1].The effects of the ion implantation process, however, have not been fully clarified, and a deeperinvestigation would be necessary in order to optimize the process and to truly exploit the glassuseful characteristics. We therefore report here the results of a broad optical, topographic, andstructural characterization of tellurite samples irradiated with various doses of nitrogen ions, whilekeeping constant the beam energy at 1.5 MeV. Characterization techniques have includedabsorption and luminescence spectroscopy, modal (dark-line) spectroscopy, surface profilometry,scanning electron microscopy, cathodoluminescence spectroscopy and EDX analysis
