| 摘 要： | 在载氢光纤上利用振幅掩模板来制作长周期光纤光栅，由于氢气的引入导致光纤光栅的热稳定性变差，这给制作符合要求的光纤光栅造成很大的困难。从理论和实验两个方面指出了在长周期光纤光栅的制作过程中若适当地降低长周期光纤光栅的含氢量，并灵活地运用均匀紫外曝光技术，能够明显地提高长周期光纤光栅的热稳定性。

| Abstract: | If a long-period grating is written in the hydrogen-loaded standard SM fiber, using the amplitude mask, the thermal stability will be decreased because of the presence of H 2, which makes it difficulty to fabricate an ideal long-period fiber grating (LPFG). It is pointed out both in aspects of theory and experiment that if the solubility of H 2 in the hydrogen-loaded fiber is lowered and using the technique of uniform UV exposure properly, the thermal stability of LPFG could be improved greatly. |
