摘　　要：分别对基于半导体光放大器(SOA)的交叉相位调制(XPM)型和交叉增益调制(XGM)型波长转换器提出了改进的新方案。采用非对称的马赫-曾德干涉仪(MZI)结构,实现了速率为10 Gb/s转换范围达40nm的XPM波长转换;利用SOA中的交叉偏振调制(CPM)效应,在XGM波长转换器中引入偏振控制结构,大大改善了转换性能,并在同一个波长转换器中实现了正反相的波长转换。Improved schemes are present for wavelength conversion based on cross phase modulation (XPM) and cross gain modulation (XGM) in SOA. By using asymmetric Mach-Zehnder interferometer (MZI), 10 Gbit/s XPM wavelength conversion is achieved over a probe wavelength range of 40 nm. By utilizing the cross polarization modulation (CPM) effect in SOA, conversion performance is significantly improved by introducing a polarization control structure to the original XGM converter. Both inverted and non-inverted conversion are achieved in right same the wavelength converter.
