Theoretical modelling and analysis on trapping of degree of polarization in compensation of polarization mode dispersion

A theoretical model and its simulation to investigate degree-of-polarization(DOP) trapping in local area during compensation of polarization mode dispersion are presented and carried out. The simulation results show that occurrence of unwanted local DOP maxima and local ridges depends on condition of both differential group delay and incident angle of optical signal to input PSP of fiber link.
