Polarization Mode Dispersion Measurements using Low-Coherence Interferometry

An interferometric setup for measuring Polarization Mode Dispersion (PMD), was tested. It uses a low-coherence technique in a Michelson interferometer to determine the PMD values in two reels, measuring the Differential Group Delay (DGD). The low-coherence source bounds the minimum value of DGD detected to 0,13 ps, leading to a minimum value detected around 0,14 ps. The measured PMD mean value for one reel, in ...
