Abstract
A novel method of adjusting the dispersion of fiber Bragg grating is proposed using the non-uniform stress effect. By loading the axial stress on the fiber grating coated with non-uniform copper thin-film, the induced non-uniform stress effect can realize the tunable dispersion of grating. The non-uniform copper films are plated on the outer cladding of fiber grating and the thickness of the copper film gradually changes along the grating length. Numerical models are established to analyze the dynamic tunable characteristics of such grating when loading different axial stresses on it. The model is verified by experiments.
