Damage and recovery of fiber Bragg grating under radiation environment Project supported by the Project for the State Key Laboratory of Optoelectronic Materials and Technologies of China (Grant No. 09010-32031708) and the Project for Zhuhai Key Laboratory of Center for Space Technology of China (Grant No. 71000-42080001). |
(color online) 3σ judgment for the difference of the experimental data points from the fitted values. The black squares and triangles represent the difference between the measured refractive-index variances and the fitted recovery curve for 825-nm and 835-nm gratings, respectively. They are within the region of 3σ judgment between the black dotted lines and dashed lines for 825 and 835 nm, respectively. |
