| 摘 要： | 本文对１５５０ｎｍ光纤光栅在纵向拉伸应力和侧向拉伸应力作用下Ｂｒａｇｇ波长的偏移特性进行了实验研究。当纵向拉伸应力加至３．６０Ｎ（３６７．６０ｇ）时,得到了５．０２ｎｍ的调谐范围。这可能是在相同应力作用下,目前所报道的最好结果。此外,还对光纤光栅弯曲所导致的其Ｂｒａｇｇ波长的迁移特性进行了实验研究,并比较了对光纤光栅段添加涂覆层前后的调谐情况,得到了最大为３．０２ｎｍ的皮长调谐范围。

| Abstract: | In this paper,the effects of strain on the Bragg
wavelength of fiber grating are analyzed,The strain-induced Bragg wavelength shift of a 1
550 nm fiber grating has been investigated experimentally by observing its transmission
spectrum and a shift up to 5.02 nm has been achieved.The possibilities of further
improvement of the tuning range and the relevant device applications are discussed.We also
investigated the bend-induced Bragg wavelength shift of fiber grating,and a shift up to
3.02 nm has been achieved. |
