Abstract

By joining conical single-mode fibers, a Mach-Zehnder interferometer with a refractive index (RI) sensor was produced. Sensors were made directly from conical SMFs using a Vytran engine. Compared to the single-taper sensor, the dual-taper sensor turned out to be more efficient. With a 10mm gap between the two taper sites in the dual-taper sensor arrangement, the RI fluctuation was quite noticeable. The principles underlying the design and fabrication of tapered optical fiber devices involve the manipulation of light propagation within an optical fiber through controlled geometrical changes. It Enhanced light-matter interaction for improved sensing and photonics applications. High sensitivity to external parameters such as temperature and refractive index changes. Miniaturization and integration of complex optical functionalities into compact devices. Furthermore, the versatility of tapered fiber design allows for customization to specific application requirements, offering high precision and control over device properties. To enhance the sensor’s effectiveness, we investigated how the sensitivity to changes in refractive index correlates with the diameter of the taper waist (TWD), while keeping the length of the taper waist constant. In particular, the sensor showed a RI sensitivity of 976 nm/RIU within a RI range of 0.018 to 0.071 with a taper width of 35.5 µm and a spacing of 10 mm.

Keywords: fiber taper, Mach-Zehnder (MZ) interferometer, refractive index (RI) sensor, single mode fibers (SMF).
