摘要
报道了一种基于光纤光栅的温度不敏感光分插复用器(OADM),该光分插复用器下载中心波长1 551.72 nm,邻道串扰小于-30 dB.采用两种不同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-18℃~50℃时,中心波长变化0.000 4 nm/℃,温度稳定性远高于未补偿光栅指标0.01 nm/℃.
A temperature insensitive optical add-drop multiplexer (OADM) based on fiber gratings is reported. The drop center wavelength of OADM is 1551.72 nm, and the adjacent channels crosstalk is less than 30 dB. The fiber grating is packed by using two materials with different thermal expansion coefficients. The variation in center wavelength in temperature range of 18℃-50℃ is 0.0004 nm/℃. The temperature stability is more higher than 0.01 nm/℃ for uncompensated fiber gratings.
