Ag-doped multi-component tellurite glasses were prepared by solid state electric fieldassisted (SSFA) diffusion. The silver concentration profiles after SSFA diffusion were measured by secondary ion mass spectrometry (SIMS). It is found that the SIMS depth profiles can be well fitted by a classical erfc-like function. The concentration dependence of silver diffusion coefficient has been investigated by using the Boltzmann–Matano analysis. The refractive index after SSFA diffusion is increased by Δn=0.025 (λ=1550 nm) without the glass surface being contaminated. Our results demonstrate that SSFA diffusion is a well controllable, non-destructive method to fabricate planar waveguides based on our newly developed tellurite glasses.
