| 摘 要： | Heat treatment with the presence of hydrogen (H2) that react with GeE' centers (Ge≡) at high temperature will weaken the refractive index modulation of grating fabricated in hydrogen-loaded normal germanosilicate fiber. Pre-annealing treatment of the above fiber was demonstrated to be able to enhance the grating's thermal stability effectively. 0.37-nm blue-shift of the reflected Bragg wavelength was observed. |

| Abstract: | Heat treatment with the presence of hydrogen (H2) that react with GeE' centers (.Ge ≡) at high tem-perature will weaken the refractive index modulation of grating fabricated in hydrogen-loaded normalgermanosilicate fiber. Pre-annealing treatment of the above fiber was demonstrated to be able to enhancethe grating's thermal stability effectively. 0.37-nm blue-shift of the reflected Bragg wavelength was ob-served. |
