	The packaging technology of optical switch arrays (EI CONFERENCE) 会议论文 OAI收割 ICO20: MEMS, MOEMS, and NEMS, August 21, 2005 - August 26, 2005, Changchun, China 作者: Chen W.; Wang W.; Zhao L.; Wang W.; Wang L. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 Optical switch is one of key supporting technologies in all-optical-network (AON). And electrostatic MOEMS (Micro-Optical-Electro-Mechanical Systems) switch plays a very important role in all the researched switches because of their excellent features including low insertion low crosstalk and scalability. But the packaging technology has been limiting the development of optical switch. In this paper the authors study the laser beam propagating during the free space and select collimator design the pedestal to packaging and address aspects of the insertion loss that are most important loss mechanisms for the 2D cross-connect switch.
