Temperature compensation technique for Bragg gratings in microstructured optical fibers for sensing applications
Résumé
The thermal drift of the characteristic wavelength of a Fiber Bragg Grating photowritten in the core of an 18-holemicrostructured fiber is significantly reduced by inserting a liquid of suitable refractive index into its holes. The maximum sensitivity is reduced, and the spectral range of variations is divided by a factor of 8, over a temperature range larger than 20°C. Such passive FBG temperature compensation technique is of great interest for applications involving accurate sensing free of thermal effects.
