Paper Abstract

A fiber-optic temperature sensor based on a pressure-induced birefringence singlemode fiber (SMF) loop mirror is developed. The pressure-induced birefringence singlemode fiber is made by applying a force against a short section of length of a singlemode fiber. The length of the sensing element for the temperature sensing is about 50 mm. Wavelength spacing between the two adjacent interference minima of the loop mirror can be tuned by varying the applied pressure. The sensitivity of the temperature measurement of 0.65 nm/oC is achieved experimentally. The proposed sensor is more convenient and simple than that of polarization-maintaining photonic crystal fiber (PM-PCF) or standard polarizationmaintaining fibers (PMF).
