A novel method for independent tuning of the center wavelength and the bandwidth of a fiber Bragg grating (FBG) was proposed and demonstrated. An FBG was adhered to the outer surface of a loop thin-wall section beam. The center wavelength and the bandwidth of the FBG can be tuned independently through changing the force while the fiber grating locates at different special positions. Quasi-chirp-free wavelength tuning with 6.706 nm and bandwidth tuning with 5.368 nm under quasi-shift-free center wavelength were obtained experimentally. The experimental results are in good agreement with the theoretical analyses.
