| 摘 要： | 本文报道了一种改变光纤光栅布喇格波长的有效方法。写于我氢光纤上的光纤光栅经过高温退火后,再利用紫外激光对其进行均匀曝光,不但能够有效改变其布喇格波长,而且还可以提高其反射效率。此种方法能很好地解决光纤光栅制作过程中的工作波长控制问题。

| Abstract: | An effective method for adjusting the Bragg wavelength of fiber grating is reported in thispaper. For annealed fiber grating written on hydrogen loaded fiber, by UV uniform exposure, theBragg wavelength can be adjusted effectively,and the reflectivity can be enhanced also. This methodsuccessfully solves the problem of Bragg wavelength controlling for fiber grating fabrication. |

| Keywords: | Fiber grating Bragg wavelength UV-exposure |
