摘要
We demonstrate an adaptive polarization control system of a 10.2 W non-polarization-maintaining fiber amplifier based on stochastic parallel gradient decent (SPGD) algorithm. The experimental investigation shows that the system can used to compensate for the polarization fluctuation of the fiber amplifier effectively and perform well over a long-time observation. When the adaptive polarization control system is in closed loop, the extinction ratio increases from 2.28 dB to 11.54 dB, and more than 93.4% of the total power in desired polarization direction is achieved.
