Abstract

The Faraday rotation is discriminated from linear birefringence in fiber current sensor by a time multiplexing of two different states of polarization at the input of the fiber. In this way an accurate current measurement can be carried out whatever the magnitude of the linear birefringence may be. A polarization multiplexing system using two identical laser diodes is presented. The experimental results and a method of compensating the imperfections of the optical components are also discussed.
