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.

A fibre Bragg grating refractometer

Measurement Science and Technology, 2001
An opto-chemical in-fibre Bragg grating (FBG) sensor for refractive index measurement in liquids has been developed using fibre side-polishing technology. At a polished site where the fibre cladding has partly been removed, a FBG is exposed to a liquid analyte via evanescent field interaction of the guided fibre mode. The Bragg wavelength of the FBG is

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.

Dispersion-free fibre Bragg gratings

OFC 2001. Optical Fiber Communication Conference and Exhibit. Technical Digest Postconference Edition (IEEE Cat. 01CH37171), 2001
Fibre Bragg gratings with reduced/eliminated in-band dispersion are presented. When tested in add-drop configurations at 10 Gbit/s both 25 GHz and 50 GHz bandwidth gratings are shown to exhibit superior performance with no dispersion-induced penalties in the stopband.
