In this paper, a cascaded Mach–Zehnder interferometer based on a photonic crystal fiber is reported. It is demonstrated that by applying a small dose of extra arc discharge to the photonic crystal fiber sensing part which is spliced to lead-in and lead-out single-mode fibers with core offset, the in-line Mach–Zehnder interferometer could be simply cascaded. From the analysis of Fourier transformed spatial spectra and the response tests as a sensor, it is shown that such a cascaded interferometer could effectively broaden the utilizable spectral shift range for a measured value.
