| 摘 要： | 建立了基于半导体光放大器交叉增益调制的波长转换理论模型，讨论了放大器的偏置电流、抽运光参数以及探测光参数对转换后信号消光比特性的影响，结果表明，大的抽运光功率小的探测光功率以及合适的转换波长间隔有利于获得大的消光比。

| Abstract: | A theoretical model of wavelength conversion based on cross gain modulation in a semiconductor optical amplifier (SOA) has been established. The influences of SOA bias current as well as pump and probe light parameters on extinction ratio characteristics of converted signals are discussed. The results show that higher pump power, lower probe power and suitable wavelength spans between pump and probe light wavelengths have the advantages to achieve the higher extinction ratio. |
