Abstract

We present a new design for an all-fiber-optic gyroscope that makes use of a single-mode coil containing a Lyot depolarizer along with a partial depolarizer placed between the polarizer and the loop coupler. This design provides an optimal trade-off between the suppression of polarization errors and the reduction of drift errors arising from external magnetic fields and changes in temperature.
