A fiber Bragg grating (FBG) fabrication method with phase mask to achieve accurate control of Bragg wavelength by measuring and adjusting the pulling force applied on a straightened fiber is introduced. The fabrication error of FBG Bragg wavelength is hold within ±0.05 nm, and FBGs with central wavelengths covering 5 nm range can be fabricated by using the same phase mask, which improves the efficiency and flexibility of the phase mask fabrication method greatly. Meantime, a novel chirped-FBG fabrication method with scanning exposure technology is put forward by varying the fiber tension during the fabrication procedure.
