Receiver-Based Localization and Estimation of Polarization Dependent Loss

Abstract: We propose a receiver-based estimator of changes in polarization-dependent loss (PDL) values of optical elements. We demonstrate that a PDL as low as 0.25dB can be localized, estimated and distinguished from a polarization-independent loss.
