Abstract

We demonstrate a novel dual-polarization interferometric fiber-optic gyroscope (IFOG), which needs only one coupler and no polarizer. Polarization nonreciprocity (PN) errors in common IFOGs will increase significantly if the polarizer is absent, or if only one coupler is used. In our setup, however, PN errors are effectively compensated by using two balanced polarizations. The 2 km coil, open-loop configuration obtains a bias instability of 0.02°/h in detecting the Earth’s rotation rate. Its performance difference from the conventional two-coupler IFOG is only a stable bias, caused by coupler nonreciprocity.

(a) The dual-polarization interferometric fiber-optic gyroscope: S, light source; PD, photodetector; SMF, single-mode fiber; PMF, polarization-maintaining fiber; PMDC, polarization-maintaining directional coupler; PZT, piezoelectric transducer. A short depolarizer is constructed with two pieces of PMF. The two pieces and the input port of the PMDC are mutually fused with a rotation angle of 45°. For comparison, we also carry out experiments while replacing the PMF pieces with (b) a conventional polarizer (P), and with (c) a polarization controller (PC).
