Abstract
When a fiber is characterized by measured polarization mode
dispersion (PMD) vector data, inversion of these data is required to
determine the frequency dependence of the fiber's Jones matrix and,
thereby, its pulse response. This tutorial reviews the principal concepts
and theory employed in approaches to PMD inversion and in the closely
related emulation of PMD. We discuss three second-order emulator models
and the distinction between the PMD vectors and the eigenvectors of the
fiber's Jones matrix. We extend emulation and inversion to fourth-order
and sixth-order PMD using higher order concatenation rules,rotations of
higher power designating higher rates of acceleration with frequency,and
representation of these rotations by Stokes' vectors.
