Analysis of polarization-maintaining photonic crystal fiber’s phase sensitivity to temperature and its influence to fiber-optic gyroscope

The polarization-maintaining photonic crystal fiber’s phase sensitivity dependence on temperature was analysis. The relationship between temperature and phase of normal polarization-maintaining fiber and polarization-maintaining photonic crystal fiber was numerical analyzed and experimental tested. Furthermore, the Shupe effects in fiber optical gyroscopes with the two fibers were studied. The contrast results showed that the phase sensitivity dependence on temperature of the polarization-maintaining photonic crystal fiber is quantitatively comparable to normal panda fiber. And the Shupe errors of the gyroscopes with the two different fibers were at the same level.
