The research discussed below describes experiments and computer simulations involving propagation of polarized radiation in optical fiber cables designed for use in aircraft environments. The main concern of this effort is optical fiber link systems that are installed in military aircraft. Propagation of polarized radiation in a single mode fiber can be theoretically described with electromagnetic field equations for a bounded system. The state of propagation of the radiation polarization will be affected by environmental stress and strain on the fiber, by imperfections within the fiber, cracks or breaks in the fiber across the fiber optical axis, and by a variety of discontinuities at fiber connectors. The transmission, reflection, and scattering of radiation within an optical fiber affected by these various effects results in mode changing of propagating radiation within the fiber. Mode changing effects by imperfection in the fiber link system have been experimentally measured. The experimental results discussed below are preliminary results and applicable to modeling techniques in the future.
