    "abstract": "One of the fundamental limitations to high bit rate, long distance,\ntelecommunication in optical fibers is Polarization Mode Dispersion (PMD). Here\nwe introduce a conceptually new method to reduce PMD in optical fibers by\ncarrying out controlled rotations of polarization at predetermined locations\nalong the fiber. The distance between these controlled polarization rotations\nmust be less than both the beat length and the mode coupling length of the\nfiber. This method can also be combined with the method in which the fiber is\nspun while it drawn. The incidence of imperfections on the efficiency of the\nmethod is analysed.",
