| 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. |
