摘　　要：设计了一种广播选择型的可重构光分插复用(ROADM)节点的体系结构,通过波长阻塞器和可调滤波器实现了动态的波长分插复用功能,讨论了基于衍射MEMS技术实现波长阻塞的原理,并对其结构进行了改进以增强系统功能。The architecture of a broadcast-and-select ROADM is proposed and the function of dynamic wavelength add/drop is carried out by wavelength blocker and tunable filter. We discuss the principle of wavelength blocker based diffractive MEMS technology and improve the structure of diffractive MEMS for system performance.
