## Abstract A novel bandwidthβtunable fiber Bragg grating (FBG) filter with fixed center wavelength is demonstrated. A linear tuning range of 7.8 nm (0.26β8.06 nm) for the 3βdB bandwidth is realized in a 10βcmβlong uniform FBG with an original 3βdB bandwidth of 0.26 nm. Reflectivity is maintained a
