摘要：

The slab waveguide of oxyfluoride glass was fabricated by Ag+-Na+ ion-exchange. The Inverse Wentzel-Kramer-Brillouin method was applied to calculate the effective indices measured with the prism coupler technique, and the refractive-index profiles were fitted using a Gaussian function. The maximum refractive-index change (Δn) and the effective diffusion constant (De) were calculated to be 0.0367 μm2/s and 0.012 μm2 s, respectively. The effect of the diffusion time on the waveguide properties was also investigated.
