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 ...

On a Mathematical Model for Fiber Tapering
SIAM Journal on Applied Mathematics, 1989 A simple extensional model for tapering optical glass fibers is derived and analysed. It is shown that, in the absence of surface tension effects, unless the initial fiber has certain spatial singularities, then the cross sectional area of the fiber cannot be made to vanish in finite time.

Tapering fibers with complex shape
Optics Express, 2010 We present a model which allows us to accurately simulate the fabrication process of complex-shaped tapered fibers. The range of possible profiles is only limited by the properties of the heat source used to shape the fiber. The model takes into account the motion of the heat source relative to the fiber as well as its temperature distribution.

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

Transmittance of tapered photonic crystal fibers with absorbing coatings [PDF]
EPJ Web of Conferences, 2020 The interaction of the adiabatically tapered photonic crystal fiber fundamental mode with a thin-film absorbing coating, deposited on a surface of a taper waist, on transmission of a tapered fiber is studied.
