Simple analysis of the distribution of birefringence in fiber optics links

In this paper, a simplified analytical method to evaluate an optical fiber birefringence was presented. It allows a significant simplification of the measurement of the spatial distribution of birefringence in optical fiber links; particularly for the small value of the birefringence. The birefringence distribution may be deduced from the calculation of the round-trip Mueller matrices derived from only two power evolution traces corresponding to the angles of the polarizer
