Paper Abstract

Metal-coated D-shape optical fiber is serving as a polarizer by using its attenuation difference for two orthogonal fundamental modes. This paper presents a novel corrosion sensor, based on an iron-coated optical fiber polarizer. The sensor is fabricated by sputtering a Fe-C film on a side-polished single mode fiber. The extinction ratio and the optical power loss are varying during the corrosion process when the iron-coated sensor is exposed to a corrosive environment. The proposed sensor provides a new approach for monitoring the early-age corrosion of steel structures by tracing the variation of polarization characteristics.
