Nonlinear switching in fibre Bragg gratings
Optics Express, 1998 We report on our recent experiments on nonlinear switching in fibre Bragg gratings. Using an all-fibre source we show an increase in transmission of a FBG from 4% to 40% at high powers. This switching is associated with the formation of gap solitons inside the grating.

Bi-Signature optical spectroscopy for online fault detection in electrical machines
The Journal of Engineering, 2019 A novel bi-signature optical spectroscopy for fault detection in electrical machines is presented. The combined use of long period grating (LPG) and two fibre Bragg gratings (FBG1 and FBG2) is implemented to discriminate between vibration and temperature

CYTOP Fibre Bragg Grating Sensors for Harsh Radiation Environments
Sensors, 2019 We present a polymer fibre Bragg grating sensor and its sensitivity to gamma radiation by observing the reflected spectral profile. The Bragg grating is femtosecond inscribed within a perfluorinated CYTOP fibre and the alteration of the Bragg wavelength ...

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