All-Order Polarization-Mode-Dispersion (PMD) Compensation at 40 Gb/s via Hyperfine Resolution Optical Pulse Shaping

For the first time, we report lightwave system experiments testing a concept for all-order polarization-mode-dispersion (PMD) compensation based on optical pulse shaping. Our results demonstrate compensation of PMD with > 50-ps average differential group delay, well into the all-order regime, in a 40-Gb/s return-to-zero on-off keying experiment.
