My. Darsht et al., OBSERVATION OF THE MAGNETIC ROTATION OF THE SPECKLE OF LIGHT PASSED THROUGH AN OPTICAL-FIBER, JETP letters, 59(11), 1994, pp. 763-765
This rotation was observed as light propagated through a few-mode opti
cal fiber in an external magnetic field. The speckle was observed in l
inearly polarized light with the same azimuthal angle as at the entran
ce to the fiber. The rotation angle corresponds in order of magnitude
and also in sign to the angle of Faraday rotation of the polarization
plane.
