A novel polarization monitoring scheme for polarization division multiplexed (PDM) systems is proposed. By using a tag light transmitted in different but close wavelength to the data signal as the feedback control, the scheme can demultiplex automatically two orthogonal polarizations in PDM systems. The effectiveness of the scheme is demonstrated experimentally in a 2?10-Gb/s on-off-keying (OOK) PDM transmission system.
