A novel all-optical header extraction scheme based on cross gain modulation and self-frequency shift in SOA is proposed and demonstrated in this paper for the first time. In the proposed technique, the header is assumed to be encoded in 2.5Gb/s PRBS and inserted ahead of a payload with 40Gb/s ratio. With theoretical simulation, the feasibility and property of the proposed scheme are demonstrated and analyzed respectively. Results indicate the performance of the technique is influenced greatly by the parameters of SOA and optical bandpass filter (OBF), such as the carrier lifetime and the 3-dB bandwidth etc. With properly chosen parameters of SOA and OBF, the transmitted energy of the payload can be suppressed effectively and the header can be extracted successfully from the input packet.
