摘要 报道了一种基于光纤光栅和环形器的高温度稳定性OADM。下载中心波长 15 5 2 .5 2nm ,邻道串扰小于 -2 5dB。采用负热膨胀系数的材料对光纤光栅进行封装 ,在环境温度范围为 -2 0℃~ +60℃时 ,中心波长变化 0 .0 0 2 2nm/℃ ,温度稳定性远高于未补偿光栅指标 0 .0 1nm/℃。 A high temperature stability OADM based on fiber gratings and circulators is demonstrated.The drop center wavelength is 1552.52nm,and the adjacent channels crosstalk is less than-25dB.The fiber grating is packed by special material with a negative thermal expansion coefficient.The variation in center wavelength over temperature range from -20℃-60℃ is 0.0022nm/℃.The temperature stability is higher than uncompensated fiber gratings 0.01nm/℃
