Abstract

In the paper we present a detailed theoretical analysis of the polarization state evolution in the all-fiber Lyot depolarizer based on a modified Mueller-Stokes equation. The results of its experimental verification are also described. Determining the exact form of the depolarization matrix diagonal elements enabled finding the formulae for the state and degree of light polarization at the Lyot depolarizer output in a function of the input light parameters and properties of the fiber used in the depolarizer construction. Finally, it is shown how this device can be used for measuring the coherence length of the light coupled into the Lyot depolarizer.
