The MZIs with different lengths are fabricated based on waist-enlarged fiber bitapers. The fast Fourier transformation is applied to the overlapping transmission spectrum and the corresponding interference spectra can be obtained via the cascaded frequency spectrum based on the inverse Fourier transformation. By analyzing the drift of interference spectra, the temperature response sensitivities of 0.063 nm\/\u00b0C, 0.071 nm\/\u00b0C, and 0.059 nm\/\u00b0C in different furnaces can be detected from room temperature up to 1000 \u00b0C, and the temperature response at different regions can be measured through the sensitivity matrix equation. These results demonstrate feasibility of multipoint measurement, which also support that the temperature sensing system provides new solution to the MZI cascade problem.<\/jats:p>","DOI":"10.3390\/s18082688","type":"journal-article","created":{"date-parts":[[2018,8,16]],"date-time":"2018-08-16T11:39:08Z","timestamp":1534419548000},"page":"2688","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["High Temperature High Sensitivity Multipoint Sensing System Based on Three Cascade Mach\u2013Zehnder Interferometers"],"prefix":"10.3390","volume":"18","author":[{"given":"Na","family":"Zhao","sequence":"first","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qijing","family":"Lin","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"},{"name":"Collaborative Innovation Center of High-End Manufacturing Equipment, Xi\u2019an Jiaotong University, Xi\u2019an 710054, China"},{"name":"State Key Laboratory of Mechanical System and Vibration, Shanghai Jiao Tong University, Shanghai 200240, China"},{"name":"State Key Laboratory of Fluid Power and Mechatronic Systems, Zhejiang University, Hanzhou 310027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhuangde","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kun","family":"Yao","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bian","family":"Tian","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0956-3833","authenticated-orcid":false,"given":"Xudong","family":"Fang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Shi","sequence":"additional","affiliation":[{"name":"Electronic Materials Research Laboratory, Key Laboratory of the Ministry of Education &amp; International Center for Dielectric Research, School of Electronic and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhongkai","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,8,16]]},"reference":[{"key":"ref_1","first-page":"415","article-title":"An electronic Mach-Zehnder interferometer","volume":"6930","author":"Ji","year":"2013","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"B\u00fchler, L., Aiello, G., Bendotti, S., Koehly, C., Mistrangelo, C., and Galabert, J.
