| 摘 要： | 提出了一种基于半导体光放大器（SOA）中交叉增益调制（XGM）效应产生高斯单边信号（monocycle）脉冲的方案。该方案只需要单个外部光源和单个SOA，结构简单；采用相向的工作方式可以改善输出信号的消光比；输出的monocycle信号光只含有一个波长，在光纤传输过程中上下脉冲不会引入时间差。利用Optisystern...

| Abstract: | We propose an ultra-wideband monocycle signal source based on the cross-gain modulation(XGM) in a semiconductor optical amplifier(SOA).In the scheme,only an optical source and a SOA are needed.So this scheme is simple.As the opposite working way is used,the scheme has advantages in improving the ER of the output signal.There is only one wavelength included in the output monocycle single pulse,so no time difference between the upper and down pulses is introduced during the transmission.By using t... |
