Abstract:
We numerically analyze the polarization-fluctuation induced bias error in a resonator fiber optic gyro (R-FOG) with twin 90° polarization-axis rotated splices in the polarization maintaining fiber (PMF) resonator, especially when polarization dependent loss (PDL) exists inside the resonator. Simulation results indicate that the twin 90° polarization-axis rotated splicing method can effectively suppress the polarization-fluctuation induced bias error in an R-FOG, when the length difference of the fiber segments between the two splicing points is set around a half of the beat-length of the PMF. It is also shown that such an R-FOG is still tolerant to PDL if the polarization crosstalk in the resonator is low, although PDL degrades the performance of the R-FOG.
