摘要：

The thermal drift of the characteristic wavelength of a Fiber Bragg Grating photowritten in the core of an 18-hole microstructured 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 ram larger than 20 degrees C. Such passive FBG temperature compensation technique is of great interest for applications involving accurate sensing free of thermal effects.
