In-line arrangement for measuring polarization extinction ratio
An in-line polarization extinction ratio (per) monitor that generates a value of an optical signal's per from a single measurement, without requiring the optical transmission signal path of the system to be directly coupled into a separate measurement device. The polarization extinction ratio may be defined as: 10 log(pex/pey), where pex is the power of the optical signal propagating along the “x axis” and pey is the power propagating along the orthogonal “y axis” (with the z-axis defined as a longitudinal optical axis of the system and the x-y plane orthogonal to this direction of propagation).
