Paper Abstract

In this paper, a novel Modal decomposition (MD) method based on the Wigner representation of fiber modal field is developed. An important distinction between this work and some others is that it can allow either fully or partially spatial coherent modal contents to be decomposed into guided modes. When the Wigner representation is reconstructed, based on the orthogonal property of guided modes and Moyal identity rule, the modal weights and possible relative phases can be obtained in an exact way. Further, the validity and reliability of the method are demonstrated with the numerical simulations.
