Abstract :
Based on a Sagnac birefringence loop composed of polarization-maintaining photonic crystal fibers, we have demonstrated a temperature-insensitive polarimetric fiber strain sensor with the reduced length of the sensing fiber, which had a sensitivity of 1.91 pm/με and a measurement range of 0~6 mε.
