We demonstrate a phase-shifted fiber Bragg grating with a taper induced by femtosecond laser micromachining. In this configuration, a fiber taper fabricated by an arc discharge in a fiber splicer was sandwiched between two fiber Bragg grating sections, which were formed using femtosecond laser line-by-line inscription. The degree of phase shift produced by this device can be adjusted by introducing axial strain, with a sensitivity of 4.59 pm/με. A theoretical study was also conducted by modeling the taper under axial strain. The relative deviation between simulated and measured sensitivities is less than 10%.
