摘　　要：着重讨论温度对光纤光栅的稳定性和反射谱的影响。分析了温度变化引起光纤光栅布喇格波长漂移的机理 ,为提高光纤光栅稳定性 。The influence of temperature and strain change on the stability and reflection spectrum of fiber gratings are analized emphatically. The excursion mechanism of Bragg wavelength with temperature variation for a fiber grating is analyzed. Then, for increasing the stability of fiber gratings, a strain compensation method for minimizing Bragg wavelength excursion is proposed.
