Hydrostatic pressure sensitivity of standard polymer fibre Bragg gratings and etched polymer fibre Bragg gratings

SPIE Proceedings, 2014
The hydrostatic pressure sensitivity of polymer optical fibre Bragg grating of different diameters is investigated. For this purpose Bragg gratings are inscribed in single-mode polymer fibre and also in etched single-mode polymer fibre. The inherent pressure sensitivity of the grating are experimentally investigated up-to 1MPa by monitoring the change ...

Regenerated femtosecond fibre Bragg gratings

SPIE Proceedings, 2012
We demonstrate the thermal regeneration of fibre Bragg gratings inscribed by direct writing using a femtosecond, infrared laser into standard SMF-28 and pure silica core fibres. Post-H2 loading was used. The regeneration process is shown to extend the temperature operation of these gratings up to 1200°C.

Interrogation of fibre Bragg gratings with a tilted fibre Bragg grating

Measurement Science and Technology, 2004
A new and efficient interrogation scheme suitable for monitoring the Bragg wavelengths of multiplexed fibre Bragg gratings is presented. The heart of the technique consists of a tilted and chirped fibre Bragg grating placed in front of a photodetector linear array.

Sinusoidally Chirped Fibre Bragg Gratings

Chinese Physics Letters, 2003
A sinusoidal chirp structure is proposed to improve the performance of fibre gratings as dispersion compensators and multichannel filters. Nearly ideal reflection spectra from sinusoidally chirped fibre gratings are exhibited. The bandwidth utilization defined as the ratio of -1 dB to -30 dB bandwidths could be higher than 0.85, even up to 0.985.

Miniature all-fibre microflown directional acoustic sensor based on crossed self-heated micro-Co2+-doped optical fibre Bragg gratings

Applied Physics Letters, 2018
The large size and electromagnetic interference of microphone arrays are long standing challenges for sound source localization. Here, an all-fibre vector acoustic sensor based on crossed microfiber Bragg gratings (micro-FBGs) has been proposed and ...
