Effect of circular polarization on the propagation of light through an optical fiber
Dugin A. V., Zel'dovich B. Ya., Kundikova N. D., Liberman V. S.
The rotation of the speckle in a multimode optical fiber upon a change in the sense of the circular polarization of the propagating light has been observed experimentally. This effect had been predicted previously. In a sense, this effect is the inverse of the "Rytov" rotation of the polarization plane.
