摘要

提出了一种利用掺镱光子晶体光纤(YbDPCF)作为扭转传感器的马赫-曾德尔干涉仪(MZI)。MZI是在两根单模光纤(SMF)之间熔接YbDPCF制备的，通过在YbDPCF上施加扭转来改变光谱干涉图样。对于这种布置，获得的扭转灵敏度为0.001 nm/°。并给出了偏振态和群双折射值的实验结果。这种方法紧凑、便携、廉价，制造过程非常简单。

Torsion sensor with an Yb-doped photonic crystal fiber based on a Mach-Zehnder Interferometer

A Mach-Zehnder Interferometer (MZI) using an ytterbium doped photonic crystal fiber (YbDPCF) is presented as a torsion sensor. The MZI was fabricated by fusion splicing an YbDPCF between two single mode fibers (SMF), which spectral interference pattern is modified by applying torsion over the YbDPCF. For this arrangement the torsion sensitivity achieved was 0.001 nm/°. In addition, experimental results of polarization states and the group birefringence value are provided. This approach is compact, portable and inexpensive and it requires a very simple fabrication procedure.
