K1 Mach–Zehnder interferometer K1 Optical fiber sensors K1 Dual-core fiber K1 Ciencias tecnológicas K1 Electrónica K1 Technology K1 Electronics AB A dual-core fiber in which one of the cores is doped with Germanium and the other with Phosphorus is used as an in-lineMach-Zehnder (MZ) interferometer to perform high sensitivity strain and temperature sensing. Opposite sensitivities forhigh and low wavelength peaks were demonstrated when strain was applied. To our knowledge this is the first time thatsuch behavior is demonstrated using this type of in-line MZ interferometer based on a dual-core fiber. A sensitivity of(78±2) pm/με, between 0-950 με and (1380±20) pm/ºC between 45 and 80ºC is demonstrated. It was also demonstratedthat it is possible to use this configuration for simultaneous measurement of strain and temperature and a matrix equationto calculate them was given PB Society of Photo-Optical Instrumentation Engineers (SPIE) SN 978-162841175-1 SN 0277-786X YR 2014 FD 2014-06-02 LK http://hdl.handle.net/10017/27699 UL http://hdl.handle.net/10017/27699 LA eng NO Ministerio de Economía y Competitividad DS MINDS@UW RD 20-abr-2024
