| 中文摘要: |
| 为了解决分布式卫星光网络中频繁的信息交换和 多跳转发导致信号损伤和信道拥塞严重的问题,提 出了一种无需独立探测光源的再生波长转换方案。利用半导体光放大器(SOA)自相位 调制(SPM)效应 对光信号频谱进行展宽,再经偏移滤波后取出预变换信号；在此基础上,以预变换信号为探 测光,通过SOA的 四波混频(FWM)效应实现对原始信号的波长变换。研究结果表明,本文方案功率转换效率可 达到23dB以上, 当输入信号功率小于－23dBm时,输出信号Q因子改善超过3dB。 |

| To solve the problem that the signal injury and channel congestion in distributed satellite optical network are serious,which are caused by frequent switching and multi-retransmission,a regenerative wavelength conversion scheme without separated detecting laser is put forward.The scheme m akes use of self-phase modulation (SPM) in semiconductor optical amplifier (SOA) to broaden the spectru m of initial signals,and a pre-conversion signal is obtained as the detecting light passes through a red- shifted filter.Then the wavelength conversion is realized based on the four-wave mixing (FWM) in another SOA.The results sho w that the conversion efficiency can reach more than 23dB,and the Q factor improvemen t can be more than 3dB when input power is smaller than －23dBm. |
