摘　　要：光子晶体光纤Bragg光栅(PCFBG)是构建光子晶体光纤激光器的重要部件。利用高压载氢增敏技术和紫外聚焦加扫描写入法在光子晶体光纤上成功制作出了1 058 nm波段的Bragg光栅。同时结合理论模型,对PCFBG的性能进行了实验研究,并对光栅写入过程中存在的一些现象进行了分析。Photonic crystal fiber Bragg grating （PCFBG） is an important component to fabricate PCF laser. Using the technology of high pressure H2-loading to improve the photosensitivity and the method of UV focusing and scanning, the Bragg grating at 1 058 nm in the photonic crystal fiber is fabricated successfully. In the mean while, combined with the theory, the characteristics of PCFBG are studied experimentally and some phenomena in the process of grating writing are also analyzed.
