Abstract: An in-fiber Mach-Zehnder interferometer (MZI) for high-sensitive refractive index (RI) measurement is proposed and experimentally demonstrated. The sensing head is formed by a single-mode ...
Abstract: In this work, it is presented the fabrication of optical fiber refractometers in the infrared region based on the deposition of indium tin oxide (ITO) coatings onto optical fibers core. ITO ...
