摘　　要：综述了波分复用(WDM)系统的关键器件之一——多波长激光器,着重对现阶段WDM各种多波长光源的原理及发展状况进行了介绍,并分析了各种多波长光源方案的优缺点。通过分析比较发现,基于超连续谱的多波长光纤激光器无论在性能、复杂度和与光纤通信系统接入方面都有着无可比拟的优势,在WDM系统中有着良好的应用前景。Multi-wavelength laser, one of the key components of WDM, are presented. It includes the principle and the situation of current development for all kinds of multi-wavelength lasers. The advantages and disadvantages of each are also demonstrated. From the analysis of the introduced laser, we discover the laser based on supercontinuum have great preponderance on capability, complexity and the access of optical fiber communication system. It promises well for the anolications in WDM system.
