Measurement of second-order polarization-mode dispersion vectors in optical fibers
TL;DR: In this paper, a Muller matrices-based measurement technique was proposed for the determination of second-and higher-order PMD vectors in optical fibers, which requires the launch of only two polarizations per wavelength and uses large rotation angles as well as interleaving.
