Trends in the design of wavelength-based optical fibre biosensors (2008–2018)

open access: yesBiosensors and Bioelectronics: X, 2019
During the last decades, both governments and companies have been committed to the continuous checking of biological parameters, which can prevent extra costs to administrations. A very efficient way to address this issue is by designing biosensors. This

Long continuously chirped fibre Bragg gratings for compensation of linear- and 3rd order-dispersion

open access: yes, 1997
For the first time long broadband chirped fibre Bragg gratings with a dispersion profile designed to compensate 3rd order-dispersion are presented. These results demonstrate how the increased demands for dispersion compensation at very high bit-rates can

Gratings photowritten in ion-exchanged glass channel waveguides [PDF]

open access: yes, 1999
Gratings are photowritten in ion-exchanged glass channel waveguides. The transmission of these waveguides shows a rejection dip of almost 20dB.

Improved design of a DFB Raman fibre laser [PDF]

open access: yes, 2009
A Raman fibre laser based on phase shifted DFB structures is modelled for the first time. Using parameters of realistic devices, the model predicts low-threshold and highly-efficient laser output.

Azobenzene-based gel coated fibre Bragg grating sensor for moisture measurement [PDF]

open access: yes, 2016
A fibre Bragg grating sensor is coated with a novel polymer gel in order to investigate its suitability for nondestructive measurement of moisture in materials that can potentially lose their integrity due to moisture ingress.

Fibre Bragg gratings and their applications [PDF]

open access: yes11th International Conference on Integrated Optics and Optical Fibre Communications. 23rd European Conference on Optical Communications IOOC-ECOC97, 1997
Summary form only given. Optical fibre Bragg gratings are the most significant new fibre device since the EDFA and will have a major impact on the design and implementation of future optical networks. Applications include single and multichannel add/drop filters, EDFA gain stabilising and spectrum flattening filters, dispersion compensation, as well as

Crack Detection in Fibre Reinforced Plastic Structures Using Embedded Fibre Bragg Grating Sensors: Theory, Model Development and Experimental Validation. [PDF]

open access: yesPLoS ONE, 2015
In a fibre-reinforced polymer (FRP) structure designed using the emerging damage tolerance and structural health monitoring philosophy, sensors and models that describe crack propagation will enable a structure to operate despite the presence of damage ...

Fibre Bragg Grating Sensors for Condition Monitoring of High-Voltage Assets: A Review

open access: yesEnergies, 2023
The high-voltage (HV) assets in the existing power transmission network will experience increased electrical, thermal, environmental and mechanical stresses and, therefore, robust condition monitoring is critical for power system reliability planning ...

Dataset for centrifuge modelling of laterally monotonic loaded monopiles in saturated dense sand

open access: yesData in Brief, 2022
The presented dataset was collected in seven centrifuge tests, specifically designed for modelling the lateral response of offshore monopiles in dense sand. Two model piles with outer diameter D = 50 mm were loaded laterally at 100 × g.
