We report on the fabrication and characterization of planar waveguides in an Er-doped tungsten-tellurite glass by implantation of 3.5 MeV N+ ions. Implantations were carried out in a wide fluence range of 1·1016 ÷8 ·1016 ions/cm2. Waveguides were characterized by m-line spectroscopy and spectroscopic ellipsometry. Irradiation-induced refractive index modulation saturated around a fluence of 8 ·1016 ions/cm2. Waveguides operating at 1550 nm were obtained in that material using 3.5 MeV N+ ion implantation.
