Abstract

In this paper we describe a new kind of all fiber polarization rotator based on the Faraday effect. Dynamic rotation of 20 degree(s) are achieved with bandwidth higher than 60 kHz. The effects of bending-induced linear birefringence are explicitly taken into account for the design of the sensing coil and the optimization of the device. With this configuration we have been able to design an electrically driven polarization scrambler working to a fixed frequency of 5 kHz suitable for the reduction of Polarization Hole Burning in Erbium-Doped Fiber-Amplifiers in long haul fiber links.
