We demonstrate wideband all-order polarization mode dispersion (PMD) compensation by
applying high-speed spectral polarization sensing and ultrafast pulse shaping techniques to
characterize and correct the frequency-dependent Jones matrix associated with PMD of
optical fibers on a wavelength-by-wavelength basis. We report full compensation of~ 800 fs
pulses distorted to more than 10 ps by a PMD module with~ 5.5 ps mean differential group
delay. The sensing and compensation of Jones matrix take~ 200 and~ 500 ms, respectively.

… Here we improve our pulse measurement technique further by introducing a polarization
insensitive FROG technique and sensing the full SOP and phase spectra of pulses distorted
by all-order PMD. We demonstrate full compensation of ~ 600 femtosecond pulses passing
through a PMD emulator with ~ 1.4 picoseconds mean differential group delay (DGD), without
the need for any iteration in the compensation or measurement process. Fig. 1 shows our
experimental setup. … We use a specially designed SOP pulse shaper (shaper 1) to correct …
