Improved thermal sensitivity of fiber Bragg gratings using a polymer overlayer

Cruz, J.L., Dong, L. and Reekie, L. (1996) Improved thermal sensitivity of fiber Bragg gratings using a polymer overlayer Electronics Letters, 32, (4), pp. 385-387. (doi:10.1049/el:19960257).

Record type: Article


Fibre Bragg gratings have been shown to have a much improved thermal sensitivity when using polymer materials with large thermal expansion coefficients as driving elements. The polymers are fixed to the fibres at an elevated temperature and the fibres are under compression instead of tension at the lower temperatures subsequently used. This allows a much wider tuning range of the Bragg gratings as silica can stand much more compression than tension. A sensitivity of 0.15nm/°C in the 1550nm wavelength regime has been achieved and the Bragg wavelength has been tuned 15nm in the temperature range 0-100°C.
