提出了一种小型的实现温度补偿的光纤光栅组件.该器件包括两种具有不同热膨胀系数的物质.通过改变加在光纤光栅上的应变可以补偿温度变化引起的光栅布喇格波长的漂移.该组件在-20～40℃的温度范围内.波长变化仅有0.12nm.是未补偿光纤光栅的1/6.
A small temperature-compensated fiber grating assembly is proposed, which consists of two materials with different coefficients of thermal expansion, which can compensate the drift of the grating Bragg wavelength caused by the temperature change by changing the strain applied to the fiber grating. The components are in the temperature range of -20 to 40 ° C. The wavelength variation is only 0.12 nm, which is 1/6 of the uncompensated fiber gratings.
