Title: | Polarization-maintaining photonic-crystal-fiber-based all-optical polarimetric torsion sensor | Authors: | Fu, HY Khijwania, SK Tam, HY Wai, PKA Lu, C |
Issue Date: | 1-Nov-2010 | Source: | Applied optics, 1 Nov. 2010, v. 49, no. 31, p. 5954-5958 | Abstract: | An application of a polarization-maintaining photonic crystal fiber (PM-PCF) for torsion sensing is proposed and experimentally demonstrated. The response of the sensor is theoretically validated using the Jones matrix. High normalized sensitivity of ∼0.014/° was measured within a linear twist angle range from 30°to 70°. The sensor response was observed to be highly repeatable over a 90° twist in both the clockwise and counterclockwise directions. The proposed sensor exhibits reduced temperature sensitivity due to the low thermal coefficient of PM-PCF, making it an ideal candidate for torsion sensing. | Keywords: | Nonlinear optics Photonic crystals Polarization Sensors Torsional stress |
