摘　　要：分析了半导体光放大器交叉增益调制的基本原理 ,并利用该机制进行了 2 .5Gbit/s的非归零码光脉冲的波长转换 .向上波长转换间隔大于 1 4nm.最后 ,对转换信号测量了接收机入纤功率和误码率的关系曲线、光眼图、消光比和光信噪比等参数 ,结果发现转换信号眼图清晰 ,张开度大 ,消光比大于 1 0 d B,光信噪比大于 30 d B.实验表明采用半导体光放大器的交叉增益调制可以较理想地实现 2 .The basic principle of all optical wavelength conversion based on cross gain modulation in semiconductor optical amplifier is analyzed and the wavelength conversion experiment has been performed for 2.5 Gbit/s NRZ optical pulse using XGM. The up conversion space is more than 14 nm. The eye diagram of the converted signal is very clear and apparently open. The extinction ratio and the optical signal to noise ratio are also more than 10 dB and 30 dB, respectively.
