Abstract
As high-precision fiber optic gyroscopes, especially three-axis high-precision fiber optic gyroscopes, face harsh electromagnetic environments, Y-junctions have become a key component that affect the precision of fiber optic gyroscopes. A high extinction ratio Y-junction is fabricated to suppress the polarization mode coupling of the fiber optic gyroscope and reduce the noise of the fiber optic gyroscope. The experimental results show that the above methods effectively solve the effect of the deterioration of the precision of the fiber optic gyroscope caused by the Y-junction.
