The Gemfire Cyclic Arrayed Waveguide Grating (AWG) is a cost-effective, high-performance DWDM mux/demux device operating on 50GHz or 100GHz chan-

nel spacing in the C and L Band ITU grid. The PhotonIC™ planar-processed silica-on-silicon chips comprise arrayed channel waveguides to separate or combine multiple wavelengths. Cyclic AWGs allow multiplexing and demultiplexing of multiple 8-channel sub-bands in a single device. Such AWGs considerably simplify inventory management for DWDM network providers. They also offer low insertion loss, excellent channel isolation, ease of fiber handling, and long-term reliability in a compact package. Available in several channel and package configurations, Gemfire Cyclic AWGs are particularly ideal for OADM appli-cations.
