Optical Code Label Stripping based on SOA-MZI in Optical Packet Switching Networks

As an alternative to label swapping, an all-optical label stripping scheme based on SOA-MZI is proposed. The stripping process is self-controlled without any synchronization process. Simulation results show that high-quality stripping can be achieved, with no more than 0.09 dB of power fluctuation and 0.05 dB of phase fluctuation in stripped and remaining label. A power contrast ratio of 28 dB between the remaining and residual stripped label, and 30-dB signal-to-noise ratio can be reached, respectively. Parameters tolerance analysis shows that the stripping performance deteriorates little when considering the devices' imperfection in practice. The multihop simulation results also show that our scheme is applicable to large-scale optical packet switching networks.
