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.   Limitations of Energy Acquisition and Energy Use in Small Poikilotherms:Evolutionary Implications 期刊论文  OAI收割 Functional Ecology, 1991, 卷号: 5, 期号: 2, 页码: 234-240 作者:  W.
