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.   Packaging technology of polymer/Si arrayed waveguide grating and their environmental stability (EI CONFERENCE) 会议论文  OAI收割 2005 6th International Conference on Electronics Packaging Technology, August 30, 2005 - September 2, 2005, Dameisha, Shenzhen, China 作者:  Zhang Y.;  Zhang X.;  Zhang X.;  Zhang X.;  Wang F. 收藏  |  浏览/下载：30/0  |  提交时间：2013/03/25 Future optical communication systems will use more of the exceptional high bandwidth of optical fiber. Wavelength division multiplexing (WDM) systems are well suited to transport terabits of information via the fiber[1]. Multiplexers/ demultiplexers (MUX/DEMUX) are essential components for dense WDM systems. Several different kinds of multiplexer types have been developed in the past: (a) interference filters  (b) fiber gratings  and (c) planar lightwave circuit (PLC) MUX/DEMUXers[2  3]. The planar fabrication process of the last mentioned PLCs allows the realization of high performance filters with a large number of wavelength channels. Further  an integration with other optical elements seems to be possible. Arrayed waveguide gratings (AWG) are a special kind of PLC-MUX/DEMUXers  which are very attractive components for WDM systems because of their great flexibility in filter design[4  5]. Basically  an AWG is an optical spectrograph built in planar waveguide technique. Typically  AWGs works in a high grating order (50-250). For AWG multiplexer applications in communications systems a precise wavelength controllability and wavelength stability with long term is demanded. Recently  a polymeric (especially fluorinated polymer with low optical absorption loss in the infrared region) AWG has attracted much attention because of its easy fabrication  low cost possibility and a potential of integration with other polymer devices[6]. Standard AWGs  however  show a change of center wavelength with temperature. A method to prevent this temperature drift is to package the AWG together with a temperature controller in order to tune and fix the desired filter-wavelength. In this paper  a 32-channel AWG was fabricated using a cross-linkable fluorinated poly (ether ether ketone) (FPEEK)  its package technology and environmental stability were also discussed. 2005 IEEE.
