The MZI was implemented by core-offset fusion splicing one section of a NZ-DSF fiber between two pieces of single mode fibers (SMFs). Here, the NZ-DSF core and cladding were used as the arms of the MZI, while the core-offset sections acted as optical fiber couplers. Thus, a MZI interference spectrum with a fringe contrast (FC) of about 20 dB was observed. Moreover, its response spectrum was experimentally characterized to the torsion parameter and a sensitivity of 0.070 nm\/\u00b0 was achieved. Finally, these MZIs can be implemented in a compact size and low cost.<\/jats:p>","DOI":"10.3390\/s16060856","type":"journal-article","created":{"date-parts":[[2016,6,10]],"date-time":"2016-06-10T07:37:41Z","timestamp":1465544261000},"page":"856","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":51,"title":["A Core-Offset Mach Zehnder Interferometer Based on A Non-Zero Dispersion-Shifted Fiber and Its Torsion Sensing Application"],"prefix":"10.3390","volume":"16","author":[{"given":"Eduardo","family":"Huerta-Mascotte","sequence":"first","affiliation":[{"name":"Departamento de Estudios Multidisciplinarios, Divisi\u00f3n de Ingenier\u00edas, Universidad de Guanajuato, Av.
