A new method for fiber grating linear tuning is reported. The wavelength range of linear tuning is about 10 nm, and R 2=0.9998. The linear formula is obtained theoretically through the material mechanics principles for the first time to our knowledge. This method will have its important application prospects in the area of fiber sensing, fiber communication, lasers and etc.
