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 ...

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

Fiber taper characterization by optical backscattering reflectometry
Optics Express, 2017 Fiber tapers provide a way to rapidly measure the spectra of many types of optical microcavities. Proper fabrication of the taper ensures that its width varies sufficiently slowly (adiabatically) along the length of the taper so as to maintain single spatial mode propagation.

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.
