The authors propose a novel technique to produce adjustable chirped gratings that allows spectral width tuning without center wavelength shift. The chirp rate can be precisely tuned by bending a uniform fiber Bragg grating (FBG) surface-mounted on one side of a simply supported beam. A maximum chirp tuning with a spectral width of 18.30 nm on a uniform FBG is obtained experimentally. Compared to the existing chirp tuning techniques, the proposed technique provides larger tuning range and smaller center wavelength shift.
