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.
