Abstract

A wavelength demodulation detection scheme was proposed based on the polarization mode interference in polarization maintaining optical fiber (PMF), and the sensing equation was obtained. Compared to the conventional intensity-based detection technique, this wavelength demodulation technique overcomes the effect of the source power fluctuation and the variation of optical loss that occurs in the transmission fiber. An experiment system was setup and the relationship between the frequency of wavelength domain and temperature was obtained within the temperature range -40°C to 80°C. Experimental results agree well with theoretical prediction.
