| Abstract: | Two methods are proposed to generate ultra-wideband(UWB) signal using different gain effects of the semiconductor optical amplifier(SOA).One is realized by utilizing two laser diodes and the cross-gain modulation effect of SOA.The other is to generate UWB signal by utilizing one laser diode and the gain saturation effect of SOA.The principles of the two methods are analyzed and simulations based on the proposed methods are carried out.Two UWB signals which meet the criterion of the U.S.Federal Communication... |
