Fiber-ring interferometer: polarization analysis

Key Points

• The study aims to analyze how polarization elements improve phase stability in a fiber-optical Sagnac interferometer affected by external factors.
• Implemented polarizing elements at both ends of the fiber to analyze their effect on phase stability.
• Monitored the impact of temperature fluctuations and mechanical vibrations on birefringence.
• Used phase shifts caused by rotation to measure the effectiveness of polarization.
• Insertion of polarizing elements led to a significant reduction in phase shifts caused by temperature fluctuations.
• Mechanical vibrations had a lesser impact on phase stability after the polarizing elements were used.
• The overall phase stability improved, enhancing the interferometer's performance for sensing applications.
