Polarization-maintaining fiber optic temperature sensing
Abstract: A high-sensitivity all-fiber temperature sensor based on a Sagnac interferometer is demonstrated by splicing a section of polarization maintaining fiber (PMF) between two sections of standard single mode fibers (SMFs). A D-shaped polarization-maintaining fiber (PMF) as fiber optic sensor for the simultaneous monitoring of strain and the surrounding temperature is presented. A mechanical end and edge polishing system with aluminum oxide polishing film is utilized to perform sequential polishing on one side. An optical fiber ring laser (FRL) cavity-based sensitive temperature and salinity sensor is proposed and experimentally demonstrated. In this sensor, the SMF-PMF-SMF structure in the Sagnac loop is bent. Polarization-maintaining (PM) fiber is engineered to preserve the state of polarization (SOP) of light as it propagates, making it a foundational component in high-performance photonic systems.
