Paper Abstract

Photonic generation of ultra-wideband (UWB) pulse technology is the key technology of UWB-over-fiber system. The effect of nonlinearity in semiconductor optical amplifier (SOA) is widely applied in the area of all-optical signal processing. A method is proposed to generate UWB doublet pulse using cross-gain modulation (XGM) of SOA and self gain-saturation (SGS) effect of SOA. In this method, the UWB monocycle pulse is generated by SOA-XGM, and the UWB doublet pulse is generated by utilizing the generated UWB monocycle pulse and gain saturation effect of another SOA. According to the proposed method, we obtained the UWB doublet pulse by utilizing photonic simulation software. The center frequency is 4.85GHz and the fraction bandwidth is 122%, it meets the criterion of FCC.
