In the present paper, we report an experimental study on a special glass developed for Ag+-Na+ ion-exchange. The glass composition and the influence of each element of the composition on the diffusion parameters were studied. Some parameters of exchange are determined, as well as the diffusion coefficient, refractive index variation, propagation and coupling losses. Such parameters can determine the fabrication conditions of integrated devices. The obtained waveguides have low coupling and propagation losses. The behavior of the fabricated waveguides at low temperatures is tested. It observed that, at these temperatures the diffusion is not negligible, which can affect the life time of the components. In order to improve this parameter, a modification of the amount of some elements of the glass composition is necessary, specially the alumina.
