摘要

介绍了一种基于选择性填充光子晶体光纤(SF-PCF) Sagnac干涉仪的高灵敏度应变传感器。SF-PCF是通过将高折射率液体渗透到最内层的两个对称气孔中来实现的。测量结果显示了超高的甚至理论上无限的条纹灵敏度。实验获得了25 pm/με的高应变灵敏度。

A high sensitivity strain sensor based on a selective-filling high birefringent photonic crystal fiber Sagnac interferometer

A high sensitivity strain sensor based on a selective-filling photonic crystal fiebr (SF-PCF) Sagnac interferometer was demonstrated. The SF-PCF was achieved by infiltrating a high index liquid into two symmetrical air holes of the innermost layer. Numetrical results revealed an ultrahigh even theoretically infinite strian sensitivity. A high strain sensitivity with 25 pm/με was experimentally achieved.
