A high-speed fiber polarization controller with high accuracy

Abstract

An all-fiber polarizing controller scheme with high speed and high accuracy is proposed. The stability is tested in detail and the system can compensate for the birefringence effects induced by the deformation of the fiber automatically. The system is simple and has high accuracy and efficiency. A preliminary experiment demonstrates that it reaches an high extinction ratio of 31 dB. The experimental results show that this system has prospects for practical applications.
