Design and Fabrication of Tapered Optical Fiber Related Devices
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 …
