Abstract
We demonstrate a femtosecond laser microfabricated fiber Mach–Zehnder interferometer and reveal the dependences of the sensitivities of different environmental parameters on the specifications of the interferometer. A 30-mm-long fiber interferometer at a wavelength of exhibits a temperature sensitivity of , axial strain sensitivity of , and refractive index sensitivity of , respectively. In addition to dependence on interferometer length, the sensitivities are also strongly dependent on the operation wavelength of the selected interference order. When the operation wavelength is selected at , the sensitivities are , , and , respectively.
