Automatic Demultiplexing Method for NRZ-OOK and RZ-OOK Polarization-Division Multiplexed System
We propose a new automatic optical polarization demultiplexing method for NRZ-OOK and RZ-OOK polarization division multiplexed (PDM) system. The detected power differences of the radio frequency (RF) at low frequency are used as control signals which are sensitive to the angles between the states of polarization (SOP) of the polarization controller (PC) and the polarization beam splitter (PBS) at the demultiplexing side. The characteristics of the detected RF signals of NRZ-OOK and RZ-OOK are compared, and the best RF detection windows are calculated out through system simulation.
