High Sensitivity Fiber Interferometric Strain Sensors Based on Elongated Fiber Abrupt Tapers
Micromachines, 2022 We demonstrate high-sensitivity fiber strain sensors based on an elongated abrupt taper. The fiber abrupt taper, with a tapered diameter ranging from 40–60 μm, was made by using a hydrogen microflame to break the waveguide adiabaticity so as to convert ...

Tapered optical fiber for Micro-Newton force sensor [PDF]
EPJ Web of Conferences, 2020 We used Brillouin scattering in silica nanofiber to demonstrate a microNewton force sensor having weak optical losses and using only one access of the nanofiber. The measurements are in good agreement with the theoretical model.

Performance Analysis of the Four-Wave Mixing Effect with Various Tapered Fiber Waist Diameters
Photonics, 2023 In this work, we report the use of different waist diameters of tapered fiber to generate a four-wave mixing (FWM) effect. The FWM conversion efficiencies obtained from the tapered fiber with 10 µm, 20 µm, and 30 µm waist diameters were −37.81 dB, −38.50

Chemical tapering of polymer optical fiber [PDF]
EPJ Web of Conferences, 2017 Les fibres optiques polymères (POF) présentent des avantages significatifs par rapport à de nombreuses applications de détection. L'élément clé dans le développement du capteur est le retrait de la gaine de la fibre. L'utilisation de solvant organique est l'une des méthodes pour créer un POF conique afin d'exposer la région centrale.
