摘要：

研制了一种宽调谐光纤光栅滤波器。该滤波器通过光纤插芯导引光栅，利用轴向压缩技术，实现了25nm的调谐。调谐过程中，FBG布拉格波长改变量与微位移台调节量呈良好的线性关系，FBG反射率波动小于0.59dB，3dB带宽波动小于0.1nm，装置稳定性较好，布拉格波长在30分钟内的漂移量小于0.07 nm。

Abstract:

A compact Bragg grating filter with a widely tuning range was demonstrated. The filter may be continuously tuned in spectral range of 25nm by applying the axial compression on the fiber Bragg grating (FBG) which is guided with two special ferrules. Our experimental results show that, the Bragg wavelength of the FBG changes linearly with the axial compression displacement. The variations of the reflectivity and the 3dB bandwidth of the FBG are respectively less than 0.59dB and 0.1nm during the tuning process. The tunable filter is stable and the Bragg wavelength shift in 30min is less than 0.07nm.

Key words: fiber and waveguide optics, tunable FBG, axial compression, Bragg wavelength, reflectivity
