Theoretical modeling and simulation for analysis of trapping of degree of polarization during polarization mode dispersion compensation

Abstract

Theoretical modeling and simulation for investigating degree-of-polarization trapping in a local area during compensation for polarization mode dispersion are presented and performed. The simulation results show that the occurrence and the characteristics of unwanted local convergent peaks and ridges depend on both the differential group delay and the launch angle of the optical signal relative to the input principal state of polarization of the fiber transmission link and that the angle required to escape from those local trapping areas can be determined.
