Fabrication Quality Assessment Based on the Coupling of a Dual-Core Microstructured Polymer Optical Fiber
(MDPI, 2021-11-09)
In this paper we report on the theoretical analysis and fabrication of a dual-core microstructured polymer optical fiber (mPOF) and demonstrate how the coupling characteristics of a dual-core mPOF may be a key factor to ...
Coupled-core fiber Bragg gratings for low-cost sensing
(Nature Research, 2022)
[EN] Sensors based on Bragg gratings inscribed in conventional single mode fibers are expensive due to the need of a sophisticated, but low-speed, interrogation system. As an alternative to overcome this issue, in this ...
Sensitivity-optimized strongly coupled multicore fiber-based thermometer
(Elsevier, 2022-01)
[EN] In this paper, we report on a multicore fiber-based (MCF) temperature sensor that operates in a wide thermal range and that is robustly packaged to withstand harsh environments. To develop the sensor, the fundamentals ...
Composed multicore fiber structure for direction-sensitive curvature monitoring
(2020-07-01)
The present work deals with a curvature sensor that consists of two segments of asymmetric multicore fiber (MCF) fusion spliced with standard single mode fiber (SMF). The MCF comprises three strongly coupled cores; one of ...
Sensing Applications in Aircrafts Using Polymer Optical Fibres
(MDPI, 2021-05-21)
We report on recent advances in the use of inexpensive polymer optical fibres (POFs) for sensing applications in avionics. The sensors analysed in this manuscript take advantage of the unique properties of polymers, such ...
Compact Omnidirectional Multicore Fiber-Based Vector Bending Sensor
(Nature, 2021-03-16)
We propose and demonstrate a compact and simple vector bending sensor capable of distinguishing any direction and amplitude with high accuracy. The sensor consists of a short segment of asymmetric multicore fiber (MCF) ...
A method for the controllable fabrication of optical fiber-based localized surface plasmon resonance sensors
(Nature, 2022)
[EN] Optical fiber-based Localized Surface Plasmon Resonance (OF-LSPR) biosensors have emerged as an ultra-sensitive miniaturized tool for a great variety of applications. Their fabrication by the chemical immobilization ...
Multi-parameter optical gauge based on mode coupling effect in asymmetric index multi-core fibres
(Elsevier, 2022-07)
An optical gauge based on coupled multi-core fiber is proposed and experimentally demonstrated. By using direct laser writing to selectively break the fiber index profile symmetry, asymmetric mode coupling between cores ...
Swin transformer for fast MRI
(Elsevier, 2022-07)
Magnetic resonance imaging (MRI) is an important non-invasive clinical tool that can produce high -resolution and reproducible images. However, a long scanning time is required for high-quality MR images, which leads to ...
Context-Aware Policy Analysis for Distributed Usage Control
(MDPI, 2022-09-27)
To boost data spaces and benefit from the great opportunities that they present, data sovereignty must be provided by Distributed Usage Control (DUC). Assuming that DUC will be managed by implementing and enforcing policies, ...
