In this paper, the fabrication of silver-sodium ion-exchange glasses is investigated. In the ion exchange process, with the placement of silver ions in the glass structure, due to the excitation of surface plasmon resonance of silver nanoparticle in glass, the absorption peak of silver ions has increased at their characteristic wavelength. Annealing the ion-exchange glasses lead to the conversion silver ions to neutral atoms and the absorption peak associated with silver atoms appears in the absorption spectrum of the annealed samples. In the next step, silver chloride thin film loaded with silver nanoparticles is deposited on ion exchange glass. The Al-AgCl thin film acts as a coupler for the ion-exchange waveguide. By measuring the periodicity of periodic nanostructures induced by laser beam on the surface of substrate, the effective refractive index of silver-sodium ion exchange glass is obtained.
