| 摘 要： | 报道了一种用高频CO2激光器在有纳米环结构的新型弯曲不敏感光纤上写入的长周期光纤光栅。实验表明只有周期在两个特定的范围内的长周期光纤光栅在1200-1650nm波长范围内会有明显的谐振峰出现。对两个周期分别为295μm和470μm的长周期光纤光栅的温度和应变特性进行了研究。实验结果显示周期为295μm的长周期光纤光栅的...

| Abstract: | Long-period fiber gratings（LPFGs） written in nano-engineered bend insensitive single-mode fiber were reported. It is found that only when the pitches of the gratings are in two special ranges obvious resonance peaks can be obtained within the band of 1 20 |
