摘要：

A novel refractive index profile, consistent with nonlinear diffusion processes in glass, is proposed for graded index (GRIN) planar waveguides. This new profile matches with great accuracy most of the waveguides fabricated by ion-exchange in glass, and it provides simple relationships between the real diffusion parameters and the effective ones obtained by fitting to the experimental results. In this way, physical parameters such as the diffusion coefficients can be easily determined and the numerical solution, describing the ion-exchange process, can be directly selected.
