Sub-Nanometer Acoustic Vibration Sensing Using a Tapered-Tip Optical Fiber Microcantilever

open access: yesSensors, 2023
We demonstrate a highly sensitive acoustic vibration sensor based on a tapered-tip optical fiber acting as a microcantilever. The tapered-tip fiber has a unique output profile that exhibits a circular fringe pattern, whose distribution is highly ...

Investigation on characteristic of LED power density via tapered fiber

open access: yesMaterials Research Express, 2022
In this paper, a tapered fiber for improving the power density of the Light Emitting Diode (LED) was designed. Numerical simulation showed that the tapered fiber makes the LED diverging light sources converge on the microscopic area, which makes the LED ...

Tapered silicon optical fibers [PDF]

open access: yesOptics Express, 2010
The tapering of silicon optical fibers is demonstrated using a fusion splicer. The silicon fibers are fabricated using a high pressure chemical deposition technique to deposit an amorphous silicon core inside a silica capillary and the tapering is performed in a separate post-process.

Analysis of Confinement in Dual Spherical-Tapered Ended Fiber Optical Trap

open access: yesApplied Sciences, 2022
In dual-fiber optical traps, two counter-propagating laser beams emitted from opposing laser fibers trap and manipulate particles. We describe the operation and performance of a dual-fiber optical trap created using spherical-tapered ended fiber ...

Flexible minimally invasive coherent anti-Stokes Raman spectroscopy (CARS) measurement method with tapered optical fiber probe for single-cell application

open access: yesPhotoniX, 2022
We proposed and demonstrated a flexible, endoscopic, and minimally invasive coherent anti-Raman Stokes scattering (CARS) measurement method for single-cell application, employing a tapered optical fiber probe. A few-mode fiber (FMF), whose generated four-

Spatial Beam Self-Cleaning in Bi-Tapered Multimode Fibers

open access: yesPhotonics, 2021
We report the spatial beam self-cleaning in bi-tapered conventional multimode fibers (MMFs) with different tapered lengths. Through the introduction of the bi-tapered structure in MMFs, the input beam with poor beam quality from a high-power fiber laser ...

On a Mathematical Model for Fiber Tapering

open access: yesSIAM 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.

High Sensitivity Fiber Interferometric Strain Sensors Based on Elongated Fiber Abrupt Tapers

open access: yesMicromachines, 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 ...
