“…A PMF resonator with 0°polarization-axis splices will support two orthogonal ESOPs even if the input lightwave is linearly polarized along one of the polarization axes of the fiber because of the misalignment of polarization-axis rotated splicing and the polarization crosstalk at the coupler [12]. While the unwanted ESOP can be sufficiently suppressed if an in-line polarizer whose orientation corresponds to the input lightwave is inserted into the resonator, and so is the polarization-fluctuation-induced drift.…”

A method to suppress the polarization-fluctuation-induced drift in a resonator fiber-optic gyro is proposed in this paper. By inserting one in-line polarizer whose polarization extinction ratio is 30 dB into a polarization-maintaining fiber resonator with 0° polarization-axis splices, the unwanted resonance is introduced to high loss and therefore the ratio of the resonance height of the desired eigen-states of polarization (ESOP) to the unwanted ESOP is 74 dB theoretically; thus the polarization-fluctuation-induced drift is adequately suppressed. The new scheme has excellent operability and high temperature stability simultaneously. Compared to the resonator with twin 90° polarization-axis rotated splices, this scheme does not need precise length difference control. This work is of great importance in the research on resonator integrated optic gyros.

“…This can be done using all polarization maintaining fiber ring resonators [11], but since the birefringence is subject to change with the temperature, a small crosstalk between the ESOP's results in non-negligible interferometric noise [12], [13]. Several papers proposed to suppress one ESOP using either polarizing fibers [14] or an anisotropic coupler [9], but the ESOP's orthogonality is removed and their differential round-trip loss must be at least of 10 dB [9].…”

Abstract-A complete analysis of the eigenstate of polarization (ESOP's) in a Brillouin fiber ring laser using fibers with a high circular birefringence is proposed in this paper. Conditions to obtain circular ESOP's for application in a Brillouin fiber optic current sensor are highlighted as well as conditions to have stable ESOP's for applications in other passive or active sensors. Measurements are performed on a Brillouin laser using a mechanically twisted fiber ring resonator confirming the theoretical predictions. Ring resonator configurations using linearly birefringent fibers are compared to configurations using circularly birefringent fibers.Index Terms-Brillouin scattering, optical fiber birefringence, optical fiber devices, optical fiber lasers, optical fiber polarization, optical resonators, optical scattering.

“…This SOP does not change its SOP shape when it takes one round trip in the resonator, which is the condition required to make the resonance [38]. The resonance point of the two ESOPs can cross each other, due to the temperature change, which makes quite a large gyro drift [42]. Two ESOPs are the eigen vectors of the transfer matrix of the polarization in the resonator, so the two ESOPs are orthogonal each other.…”
