(color online) Refractive-index variation with respect to the radiation time after recovery correction. The black squares and triangles represent the refractive-index data with respect to time (different doses) for 825- and 825-nm gratings, respectively. The black line and dashed line are the curves fitted using the color-center creation model for 825 and 835 nm, respectively.
