| Title: | Temperature-insensitive strain sensor with polarization-maintaining photonic crystal fibre based Sagnac Interferometer | Authors: | Dong, X Tam, HY Shum, P |
Issue Date: | 9-Apr-2007 | Source: | Applied physics letters, 9 Apr. 2007, v. 90, no. 15, 151113, p. 1-3 | Abstract: | A fiber-optic strain sensor is demonstrated by using a short length of polarization-maintaining photonic crystal fiber (PM-PCF) as the sensing element inserted in a Sagnac loop interferometer. Spectrum shift in response of strain with a sensitivity of 0.23 pm/με is achieved, and the measurement range, by stretching the PM-PCF only, is up to 32 mε. Due to the ultralow thermal sensitivity of the PM-PCF, the proposed strain sensor is inherently insensitive to temperature, eliminating the requirement for temperature compensation. | Keywords: | Strain sensors Fibre optic sensors Photonic crystals Optical fibre polarisation Sagnac interferometers Spectral line shift |
