摘　　要：分别采用丙烯酸类聚合物与硅树脂材料实现了长周期光纤光栅 (LPFG)的大范围波长调谐与温度补偿 .当温度从 0～ 1 0 0°C变化时 ,对于表面涂覆丙烯酸类聚合物的 LPFG,波长调谐范围增大至 6 0 nm;而对于涂覆硅树脂的 LPFG,同样的温度变化波长漂移则被抑制在 0 .6 nm之内 .前者提供一种大范围波长调谐带阻滤波器或高灵敏度温度传感器的思路 ;后者可考虑进一步改进后用作经温度补偿的滤波器。Both acrylate-based polymer and silicone resin were proposed as recoating materials for broadband wavelength tuning and temperature compensation of LPFG. The range of wavelength shift as much as 60 nm is expected for the LPFG recoated with acrylate-based polymer when temperature changes from 0~100°C . However, for that recoated with silicone resin, the temperature sensitivity is suppressed with about 0.6 nm of the maxium wavelength shift with the same temperature variation. The former is potentially a broadband tunable band rejection filter or temperature sensor with enhanced sensitivity. While the latter could be modified as a temperature insensitive filter, demultiplexer or stain sensor.
