Characterization of ion diffusion process in glasses with simple mode-index measurements
Source abstract
Abstract
It is shown by numerical computations that self-similar index profiles imply self-similar mode spectra in planar waveguides. This leads to a simple method to estimate the diAusion activation energy and to evaluate the validity of Fick’s second law in diAusion modeling, under given processing condition, from measurements of mode spectra. The feasibility of the approach is verified experimentally with Na2O‐SiO2‐Al2O3‐B2O3 glass developed for ion exchange processing. ” 2000 Elsevier Science B.V. All rights reserved.
