Abstract
A magnetic drift that linear to orthogonal magnetic field (OMF) is induced by OMF which is parallel to the sensitive axis of the depolarized FOGs. As winding a fiber coil causes the refractive index near the center to increase and away from the center to decrease, by placing a short segment of special fiber at the end of the coil, the magnetic drifts induced by OMF in the special fiber and that in the single-mode fiber (SMF) are equal in magnitude but opposite in signs, which means the summation of the two magnetic drifts is zero. Therefore the goal of compensating magnetic drift induced by OMF in depolarized FOG is successfully achieved.
