摘　　要：AOWC(全光波长转换)是WDM(波分复用)光纤通信网络中的一项核心技术,基于FWM(四波混频)的AOWC能够保持信号原有的振幅、相位和偏振方向,适用于高频谱效率的高级调制格式信号波长转换。文章系统地总结了基于FWM实现各种高级调制格式信号波长转换的研究进展,对各种方案的特点进行了比较分析,最后探讨了提高器件实用性和可靠性的方法。All-Optical Wavelength Conversion （AOWC） is a core technology for WDM fiber-optic communication networks. As Four-Wave Mixing （FWM）-based AOWC can maintain the original amplitude, phase and polarization direction of signals, it is appropriate for advanced modulation formats with high spectral efficiency. This paper systematically summarizes the research advances in signal wavelength conversion in various FWM-based advanced modulation formats and compares and analyzes the advantages and disadvantages of various schemes. Finally, it discusses the methods for improving the applicability and reliability of the devices.
