摘　　要：伴随着光纤通信技术的发展,光纤Bragg光栅已成为光纤通信的基本元件。由于光纤Bragg光栅的中心反射波长λB随着环境温度的起伏而发生漂移,为光纤Bragg光栅的应用带来很大困难。本文用负热膨胀系数陶瓷粉末ZrW2O8对光纤Bragg光栅进行了温度补偿,取得了一定的补偿效果,为深入研究奠定了一定的基础。With the development of the optical fiber communication,the optical fiber Bragg grating has become the primary element of the optical fiber communications.Because the central reflection wave length λ_B of the optical fiber Bragg grating drifts along with the ambient temperature fluctuation,it is very difficult for the application of the optical fiber Bragg grating.The temperature compensation of the optical fiber Bragg grating was carried by using negative thermal expansion coefficient ceramics powder ZrW2O8,The temperature compensation effect was obtained and it prepared the ground for deep research.
