摘要
波长选择开关(WSS)被认为是最重要的波长引擎技术,已成为运营商在下一代网络部署中的关键器件。提出了一种新型的波长选择开关结构,用基于一维的微电机系统(MEMS)转镜实现切换的功能和透射式MEMS衰减器技术实现无干扰(Hitless)功能,相对于使用二维MEMS转镜同时实现波长切换和Hitless功能的WSS。其具有技术成熟,成本相对低廉等优点。理论分析并数值模拟了该WSS的几个关键参数,实际制作并测试了这种新型的WSS,实现了最大衰减量约34 dB,插入损耗约6.4 dB,通道内色散变化范围为-1.64-6 ps/nm,与数值模拟结果能够较好地吻合。
Abstract
The wavelength selective switch (WSS) is now considered to be the most important wavelength engine technology,and will be the key component of next-generation optical networks for carriers all over the world. A novel WSS is theoretically and experimentally presented in this paper,which implements an one dimensional MEMS mirror to realize the function of wavelength switching,while the Hitless switching is achieved by a MEMS attenuator. Compared with traditional WSS implementing two dimensional MEMS mirror to achieve the two functions simultaneously,this novel WSS is manufactured based on mature technologies,so it is cost-effective and productive. The maximum attenuation of 34 dB,insertion loss of 6.4 dB,dispersion range of -1.64-6 ps/nm are reported,indicating a high uniformity with the simulation results.
