Abstract:-Photonic generation of UWB signals is the one of the key technology of UWB-over-fiber system. This paper proposes a method to generate UWB doublet signals utilizing the cross-phase modulation (XPM) in a semiconductor optical amplifier (SOA) in a NOLM. The simulation experiment based on the proposed method is carried out. UWB doublet signals which have a central frequency of 6.05GHz and a relative bandwidth of 121% are obtained in the simulation experiment. The simulation result verifies the feasibility of the… Show more
