摘　　要：为了提高温度补偿封装的可靠性,改进了光栅制备结构,使光栅在一定的预拉条件下,光栅中心反射波长能在应用要求的规定值内小范围浮动,误差控制在±0.1 nm之内。根据温度补偿比公式,设计了一种可调谐的温度补偿封装结构,温度实验证实其补偿效果达到应用要求,并证明其可调谐的精度在±0.03 nm范围内,为规范化生产可调温度补偿光纤光栅提供了一个很好的实施方案。In order to enhance the reliability of thermal compensation packaging, the fabrication structure of fiber grating is improved,so that under a certain preloading stress,the central reflection wavelength of the grating is able to vary in a small range specified by the application requirement,and the error is controlled within ±0.1 nm.Based on the formulas of thermal compensation an adjustable packaging structure with thermal compensation is designed.The thermal experiment proves that the thermal compensation effect achieves the application requirement,and the precision of the adjustable range is within ±0.03 nm,which provides a good implementation scheme for producing adjustable thermal compensation fiber grating.
