【摘要】 提出了一种简单、小型的光纤光栅温度补偿器件 ,将光纤光栅粘贴在具有负热膨胀系数的材料上 ,实现了光纤光栅的温度补偿。该器件在 - 2 0～ 4 4℃温度范围内光栅波长变化 0 .0 8nm ,是未补偿光纤光栅的 1/8。更多还原

【Abstract】 A fiber Bragg grating is bonded on special material with a negative thermal expansion coefficient. The simple and compact temperature compensation fiber Bragg grating package is demonstrated. The total variation in wavelength over temperature range from -20～44 ℃ is 0.08 nm, which 1/8 of the uncompensated fiber Bragg grating.更多还原
