摘　　要：在对长周期光纤光栅的光学特性进行分析的基础上 ,通过适当设计的程控自动扫描曝光系统 ,采用具有高度灵活性的逐点写入技术在经过氢载处理的普通单模光纤上成功地进行了长周期光纤光栅的研制。随后对氢载光纤中长周期光纤光栅的稳定性问题进行了分析与研究。The optical properties of long- period fiber gratings are studied,and long- period gratings are successfully written in the hydrogen- loaded standard single- mode fibers by a Kr F excimer laser and point- by- point method with a properly designed program- controlled auto- scanning exposure system.The experimental results show that this method is highly flexible in the fabrication of long- period fiber gratings.The stability of the long- period grat- ings written in hydrogen- loaded standard single- mode fibers are studied and discussed.
