中文摘要: 作为光网络的核心节点,具有动态配置能力的可重构光分插复用系统是光网络"智能"实现的重要基础。新型的网络业务要求下一代可重构光分插复用系统具有"四无"特性:无色、无方向、无阻塞、无栅格。目前,基于光脉冲整形技术的可重构光分插复用系统,已可实现部分"四无"特性。但可重构光分插复用系统在应用时,还存在许多问题,比如:可重构光分插复用系统链路传输损伤以及存在波长阻塞等。 本项目拟通过光脉冲整形技术对可重构光分插复用器系统的通道中心频率和带宽进行动态控制,在实现波长路由的同时,进行以下几方面的研究:(1)可重构光分插复用系统中的光性能监控及功率均衡和色散补偿技术;(2)可重构光分插复用系统中的波长冲突解决方案及波长转换器的合理配置;(3)超宽带波长转换器的基础理论研究和实验。

英文摘要: As the core node in optical network, Reconfigurable Optical Add/Drop Multiplexing (ROADM) system is the important basis of intelligent optical network. The new network services require that next generation ROADM system has four "-less": colorless, directionless, contentionless, and gridless. ROADM system based on optical pulse shaping has some of the four "-less". But there are many problems in applications, such as transmission impairment and wavelength blocking. In this project, the channel center frequency and bandwidth of ROADM system are controlled through optical pulse shaping for wavelength routing. The following research issues will be investigated: (1) optical performance monitoring, power equalization and dispersion compensation in ROADM system; (2) wavelength conflict resolution and wavelength converter configuration in ROADM system; (3) study on broadband wavelength converter theoretically and experimentally.
