Using a phase retrieval algorithm we can obtain accurate all order polarization mode dispersion (PMD) information for the optical signal and correspondingly compensate the impairment in optical transmission lines. Linear PMD is accurately extracted from measurements, and analytical simulations show recovery of pulses distorted by higher order PMD.}, language = {en} } @article{CimponeriuRosenblumPikovskij2004, author = {Cimponeriu, Laura and Rosenblum, Michael and Pikovskij, Arkadij}, title = {Estimation of delay in coupling from time series}, issn = {1063-651X}, year = {2004}, abstract = {We demonstrate that a tune delay in weak coupling between two self-sustained oscillators can be estimated from the observed time series data. We present two methods which are. based on the analysis of interrelations between the phases of the signals. We show analytically and numerically that irregularity of the phase dynamics (due to the intrinsic noise or chaos) is essential for determination,of the delay. We compare and contrast both methods to the standard cross-correlation analysis}, language = {en} }
