Abstract

The experimental and theoretical results show that polarisation dependent loss (PDL) plays a major role in the loop performance. In recirculating loop systems, the PDL will unrealistically improve the performance when the polarization evolution is optimized by using a polarization controller. The noise tends to polarize in the polarization state of the signal, and the noise orthogonal to the signal is reduced. We have characterized the behavior of the polarization state as a spiral evolution on the Poincare sphere and have associated different types of spirals with different system performance.
