Paper Abstract

A wavelength division multiplied (WDM) polarization-maintain fiber sensor system for simultaneous temperature and pressure measurement is proposed. The system comprises a PANDA fiber polarimetric temperature sensor and a highly birefringent photonic crystal fiber (PCF) polarimetric pressure sensor, which are multiplexed by use of a WDM beam splitter/combiner and interrogated in wavelength domain by using a combination of a broadband source and an optical spectrum analyzer. Preliminary experiments demonstrate a temperature sensitivity of about 1.16nm/oC and a pressure sensitivity of 2.42nm/MPa with respectively 162.7mm of PANDA fiber and 262.8mm of PCF.
