This paper reports the preparation of planar waveguides in an Er3+ doped tellurite glass with a composition, 15Na2O-25WO3-60TeO2-1Er2O 3 (mol%), by Ag+ - Na+ ion-exchange. The glass was chemically stable during ion-exchange process. Single-mode and multi-mode planar and buried waveguides in the tellurite glasses have been prepared, which is the first demonstration of waveguides in tellurite glasses fabricated by ion-exchange technique to the best of our knowledge. The depths of the waveguides could be controlled by varying ion-exchange temperatures and times (290°C to 360°C, and 1h to 34h were used in the paper). The diffusion parameters, diffusion coefficients and activation energy were estimated. It is indicated that the tellurite glass is a prospective candidate for active integrated optics.
