A Mach\u2013Zehnder interferometer is formed by splicing a section of MMF between two single-mode fibers (SMFs) and a high interference fringe of up to 15 dB is achieved. The sensing experimental results show a strain sensitivity of \u22121.17 pm\/\u03bc\u03b5 and 0.6498 pm\/\u03bc\u03b5 for the dip of MZI and Bragg peak, while a temperature sensitivity of 42.84 pm\/\u00b0C and 19.96 pm\/\u00b0C is measured. Furthermore, the matrix analysis has found that the strain and temperature resolution of the sensor are as high as \u00b112.36 \u03bc\u03b5 and \u00b10.35 \u00b0C, respectively. In addition, the sensor has merits of simple fabrication, good spectral quality, and high resolution, which shows attractive potential applications in dual-parameter sensing.<\/jats:p>","DOI":"10.3390\/s21175938","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T13:18:26Z","timestamp":1630934306000},"page":"5938","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Highly Sensitive Dual Parameter Sensor Based on a Hybrid Structure with Multimode Interferometer and Fiber Bragg Grating Fabricated by Femtosecond Laser"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1669-7004","authenticated-orcid":false,"given":"Xinran","family":"Dong","sequence":"first","affiliation":[{"name":"College of Mechanical and Electrical Engineering, Central South University of Forestry and Technology, 498 South Shaoshan Street, Changsha 410004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Zeng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High Performance Complex Manufacturing, College of Mechanical and Electrical Engineering, Central South University, 932 South Lushan Street, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dongkai","family":"Chu","sequence":"additional","affiliation":[{"name":"Center for Advanced Jet Engineering Technologies (CaJET), School of Mechanical Engineering, Shandong University, 17923 Jingshi Road, Jinan 250061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyan","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High Performance Complex Manufacturing, College of Mechanical and Electrical Engineering, Central South University, 932 South Lushan Street, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"070601","DOI":"10.3788\/COL202119.070601","article-title":"Recent advance in hollow-core fiber high-temperature and high-pressure sensing technology","volume":"19","author":"Zhang","year":"2021","journal-title":"Chin.
