The Shupe effect in a fiber optical gyroscope with polarization-maintaining photonic crystal fiber was studied. The thermal sensitivitise of the polarization-maintaining photonic crystal fiber and conventional polarization-maintaining fiber were simulated and measured. Then the Shupe error in the gyroscope was analyzed. The contrast results showed that the Shupe error of the gyroscope with the polarization-maintaining photonic crystal fiber is quantitatively comparable to that using the conventional polarization-maintaining fiber.

Key words: polarization-maintaining photonic crystal fiber (PM-PCF), polarization-maintaining fiber (PMF), fiber-optic gyroscope (FOG), Shupe error
