Simultaneous interrogation of multiple fiber bragg grating sensors using an arrayed waveguide grating filter fabricated in SOI platform [PDF]

open access: yes, 2015
A novel fiber Bragg grating (FBG) interrogator is demonstrated based on an optimized arrayed waveguide grating (AWG) filter. The AWG response is optimized to achieve large crosstalk between the output channels, which allows simultaneous detection of ...

Cladding mode coupling in highly localized fiber Bragg gratings: modal properties and transmission spectra

open access: yes, 2010
The spectral characteristics of a fiber Bragg grating (FBG) with a transversely inhomogeneous refractive index profile, differs con- siderably from that of a transversely uniform one.

High-speed interferometric FBG interrogator with dynamic and absolute wavelength measurement capability [PDF]

open access: yes, 2013
A passive, interferometric wavelength demodulation technique has been extended to measure the absolute wavelengths of a multiplexed array of fiber Bragg grating sensors. The scheme retains its original strain resolution of 10 nε/√{Hz}. A proof-of-concept

A novel application of Fiber Bragg Grating (FBG) sensors in MPGD [PDF]

open access: yesEPJ Web of Conferences, 2018
We present a novel application of Fiber Bragg Grating (FBG) sensors in the construction and characterisation of Micro Pattern Gaseous Detector (MPGD), with particular attention to the realisation of the largest triple (Gas electron Multiplier) GEM chambers so far operated, the GE1/1 chambers of the CMS experiment at LHC.

Mechanical strength of silica fiber splices after exposure to extreme temperatures [PDF]

open access: yes, 2012
By using a combination of type-I and regenerated gratings, the mechanical strength of optical fiber splices after exposure to temperatures over 1300 C was characterized. Splice strength was found to decrease with temperature with a secondorder polynomial

X-ray Writing of Fiber Bragg Gratings (FBGs)

open access: yes, 2020
Fabrication of nanoscale optical Fiber Bragg Gratings (FBGs) is one of the key manufacturing processes for fiber optics, which has many important applications in data communication and distributed remote sensing at a distance up to hundreds of kms. However, the fabrication of the FBGs is challenging.
