Abstract : This report describes a polarization modulated link and the associated polarization dependent loss, including theory. The general system is discussed as well as the details for measuring and calculating polarization dependent loss in the system. A set of experiments are presented that looks at non-ideal alignment of the polarization modulation arc. In addition to the theory for polarization distortion and a compensation technique, the system is investigated when only partially compensated for polarization dependent loss induced nonlinearity. Finally, the polarization modulator nonlinearities are investigated, with the results showing the tradeoffs for using either the DC bias of a rotating half-wave plate for bias phase control. The report also details the code that contains the model used to analyze the system.
