Home / Two fiber optic MZI sensors
In this paper, we propose and experimentally demonstrate a dual-parameter fiber optic sensor, which combines a Fabry–Perot interferometer (FPI) and a Mach–Zehnder interferometer (MZI) for simultaneous pressure and temperature sensing. A sensitivity-enhanced dual Mach–Zehnder interferometer (MZI) fiber-optic biosensing platform for highly sensitive immunoassay detection of the inflammatory biomarker serum amyloid A (SAA) is presented in this study. The sensor is fabricated by coupling and fusing the multimode fiber (MMF) with the single-mode fiber (SMF) using arc fusion technology (AFT), resulting in a. We used an optical fiber fusion splicer to directly splice a segment of FCF between two segments of NCF, with both the FCF and.
