摘　　要：　用长周期振幅掩模板(周期为500μm)和相位掩模板(周期为1.0739μm),采用曝光法制作出了1.5cm长的取样光纤光栅。测试了光纤光栅的温度特性,发现光纤光栅的反射波长随温度的升高向长波方向漂移,三个主峰波长随温度的变化规律是相同的,波长与温度有良好的线性关系,温度变化并不会引起通道间隔的变化,温度漂移系数约为0.01nm/℃。采用与Bragg光纤光栅相同的负温度系数的衬底材料来补偿中心波长随温度的漂移,封装后的取样光纤光栅的温度系数达到0.004nm/℃。A 1.5cm long sample fiber grating using long period(500μm) amplitude masks and phase masks(with the period of 1.0739μm) was fabricated by UVexposure method. The temperature response of the sample fiber grating was tested which found that the reflect wavelength of the fiber grating shifts to the long wavelength along with the increase of the temperature. The varying rule of the temperature dependence of three leading wavelengths is same and the channel spacing keeps constant. The result shows good linear...
