A bandwidth-tunable optical fiber Bragg grating filter with a large tuning range of 36 nm (1.8 - 37.8 nm) has been demonstrated, which represents, to the best of our knowledge, the broadest tuning range in reflection bandwidth of any optical fiber Bragg gratings that has been reported. The unique cantilever beam based chirp-rate tuning method used here may produce a changeable and uniform chirp rate along the length of the grating, with simultaneously keeping the center wavelength of the grating fixed. Based on this study, a spacing-tunable comb filter by using a sampled-chirped fiber Bragg grating has also been demonstrated. The change in spacing, with a tuning range up to 2.1 nm (1.2-3.3 nm), is also obtained by using the unique fiber grating chirp-rate tuning technique.
