摘　　要：　建立了基于半导体光放大器交叉增益调制(SOA XGM)的波长转换理论模型,利用分段方法对XGM波长转换器同向和相向两种工作方式下消光比特性作了详细的研究。结果表明,相同情况下相向工作方式下的输出消光比特性要优于同向工作方式的。最后,从物理上对两种工作方式消光比和噪声特性的差异做了解释。A theory model of wavelength conversion based on cross gain modulation in semiconductor optical amplifier is derived. Characteristics of extinction ratio of converted signal under both co-and counter-propagating scheme are discussed in details. It's shown that under the same condition the latter shows a better output extinction ratio. Finally, the difference between the two schemes is explained from physical point of view.
