Yalin Guan, Rui-dong Wang, Lei Zhang · 2012
A method was proposed to implement data extraction using AND optical gate based on cross gain modulation (XGM) of semiconductor optical amplifier (SOA).The optical data extraction in DPSK/ASK orthogonal modulation system was achieved with the proposed AND gates, in order to prove its feasibility.Through the simulation, the data extraction in orthogonal modulation system with a 10Gbit/s NRZ pseudo-random payload signal and 2.5Gbit/s label signal was demonstrated.
