To obtain fiber devices with large stretched amount, we designed and fabricated two kinds of chirped fiber Bragg grating (CFBG) stretchers with the phase mask inscription technology. According to the theories of the phase mask inscription technology and dispersion compensation with CFBGs, the fabrication methods for the two stretchers were proposed and the optical paths were optimized to obtain CFBGs with high reflectivity and wide reflection bandwidth. The reflective resonance wavelength of CFBG was controlled by the tension sensor, and the inscription method was improved. A cascaded CFBG stretcher with large dispersion and a series CFBG stretcher with large reflection bandwidth were fabricated. Fiber sources were then built to test the two kinds of stretchers. The stretched amount provided by the cascaded CFBG stretcher was directly measured to be 345 ps, which was consistent with the theoretical result. The stretched amount provided by the series CFBG stretcher was indirectly calculated through direct and reverse connections. The calculated result, being about 278.7 ps, was smaller than the theoretical result.
