title: Stochastic theory of the Stokes parameters in randomly twisted fiber.
abstract: We present the stochastic approach of the polarization state of an electromagnetic wave traveling through randomly twisted optical fiber. We treat the case of the weak randomness. When the geometric torsion of the fiber is distributed as a Gaussian law, we can write explicitly the Fokker-Planck equation for the Stokes parameters of the wave, and find the complete solution of the polarization-state distribution.
