Abstract
Implemented in both coherent and non-coherent optical systems, a receiving device including a cross polarization interference canceler (XPIC) is described. For these embodiments, the XPIC optimizes bandwidth efficiency of an optical communication link by enabling the reconstruction of two optical signals transmitted with generally orthogonal polarization states and routed over a single fiber optic transmission medium in the same frequency band.
