| 摘 要： | 在反向注入辅助光的条件下对基于半导体光放大器(SOA)中交叉增益调制(XGM)的全光波长转换进行了研究, 分析了该方案中转换信号的眼图消光比、信噪比与所注入辅助光的功率、波长之间的关系. 实验结果表明, 注入适当功率和波长的辅助光后, 转换信号的眼图信噪比可提高6~10 dB, 明显改善了转换信号眼图的质量, 降低了系统的误码率, 提高了系统的灵敏度.

| Abstract: | All optical wavelength conversion (AOWC) based on cross-gain modulation (XGM) in a semi-conductor optical amplifier (SOA) with assist light injection is demonstrated. The experiment shows that with less reduction of ER (1~2 dB), the SNR of detected signal can be largely im-proved (6~10 dB), so the eyegraph’s quality of detected signal and the sensitivity of the system can be improved and the system BER will be reduced slightly. |
