Abstract

Design, fabrication and application of twisted fiber for polarized light transmission and electric current sensor are presented in the paper. A characterization parameter of twist fiber is proposed for the design of twisted fiber for linearly or circularly polarized light transmission. The problem of employing twisted fiber in current sensor, e.g., the temperature or polarization perturbation induced sensor bias drifting, is overcome by a novel signal processing method with a modified optical arrangement for ac current detection. Experimental results show the compensation method is effective to arbitrary bias phase drifting in electrical current sensor using twisted fiber.
