Abstract :
A all optical header extraction scheme based on semiconductor optical amplifier and Mach-Zehnder-Interferomete (SOA-MZI) with asymmetric control light was proposed and demostrated in this paper. By theoretical analsys, we found the proposed scheme can implement the optical pakcet header extraction more effectively. Numerical analsys and simulation show that more than 18dB contrast ratio of the extrcacted header at 20Gbit/s and the suppressed payload at 80Gbit/s can be achieved. In addition, the parameters of the SOA-MZI and the input packet are discussed to optimize the performance of the scheme and the results also indicate that the performance of the scheme is influenced greatly by the parameters of SOA.
