Quadratic behavior of fiber Bragg grating temperature coefficients [PDF]

, 2004
We describe the characterization of the temperature and strain responses of fiber Bragg grating sensors by use of an interferometric interrogation technique to provide an absolute measurement of the grating wavelength. The fiber Bragg grating temperature

Magnetically programmable fibre Bragg gratings

Electronics Letters, 1998
An attractive force between magnetic poles was utilised to produce significant wavelength shifts in fibre Bragg gratings. Programmable magnets were used to controllably strain and shift the wavelength of the grating by more than 15 nm. The wavelength tuning is fast and the device requires no power to maintain the shifted wavelengths.

Fibre Bragg gratings fabrication in four core fibres [PDF]

SPIE Proceedings, 2016
Due to the limitation of the lens effect of the optical fibre and the inhomogeneity of the laser fluence on different cores, it is still challenging to controllably inscribe different fibre Bragg gratings (FBGs) in multicore fibres. In this article, we reported the FBG inscription in four core fibres (FCFs), whose cores are arranged in the corners of a
