Tapered optical fibre sensors employing nanostructured coatings [PDF]
, 2010 Tapered optical fibres have been manufactured, characterised and studied. These are compact devices made from single-mode optical fibre. A system for producing tapers has been developed, employing flame heating of the optical fibre and computer ...

Tapered Fiber Bragg Grating Fabry–Pérot Cavity for Sensitivity-Enhanced Strain Sensing [PDF]
SensorsThis paper presents a novel optical fiber axial strain sensor based on a Fabry–Perot interferometer (FPI) cavity incorporating Fiber Bragg Gratings (FBGs) and a tapered fiber, which has been experimentally validated.

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

Tapered silicon optical fibers [PDF]
Optics 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.

Tapered Fiber Bioprobe Based on U-Shaped Fiber Transmission for Immunoassay
Biosensors, 2023 In this paper, a tapered fiber bioprobe based on Mach–Zehnder interference (MZI) is proposed. To retain the highly sensitive straight-tapered fiber MZI sensing structure, we designed a U-shaped transmission fiber structure for the collection of optical ...

Numerical and Experimental Investigation on the Optical Manipulation from an Axicon Lensed Fiber
Micromachines, 2021 Here we numerically and experimentally studied the optical trapping on a microsphere from an axicon lensed fiber (ALF). The optical force from the fiber with different tapered lengths and by incident light at different wavelengths is calculated ...

Optical Gas Sensor Fabrication Based on Porphyrin-Anchored Electrostatic Self-Assembly onto Tapered Optical Fibers [PDF]
, 2012 Tapered optical fibers with nano-assembled coatings of thicknesses of order tens of nanometres were used for the detection of ammonia gas. The film coating was composed of alternate layers of tetrakis-(4-sulfophenyl) porphine (TSPP) and poly(allylamine ...
