EVALUATION OF THE SPATIAL DISTRIBUTION OF BIREFRINGENCE IN AN OPTICAL-FIBER LINK

摘要

We present a simple method of the calculation of spatial distribution of birefringence in an optical-fiber link. This method is based on an analysis of the properties of the backscattered optical signal. The analytical results are compared with the numerical results, and excellent agreement is obtained. We demonstrate that the spatial-birefringence distribution may be obtained from the calculation of the roundtrip Muller matrices derived from only two power-evolution traces, corresponding to two different angles of the polarizer.
