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。
Based on the analysis of the optical characteristics of long-period fiber gratings, a properly designed program-controlled automatic scanning exposure system was successfully implemented on a hydrogen-treated ordinary single-mode fiber using a highly flexible point-by-point writing technique The development of long period fiber grating. Subsequently, the stability of long-period fiber gratings in hydrogen-loaded fibers was analyzed and studied.
