Gemfire Athermal Arrayed Waveguide Grating

The Gemfire Athermal AWG (Arrayed Waveguide Grating) is a high-performance DWDM mux/demux device operating on 100GHz channel spacing without the need for temperature stabilization. The Gemfire PhotonIC™ planar-processed silica-on-silicon chips comprise arrayed channel waveguides to separate or combine multiple wavelengths. Athermal AWGs allow multiplexing and demultiplexing of DWDM signals over a wide range of operating temperatures, without the need for heater drive and monitoring electronics.

These AWGs offer low insertion loss, excellent channel isolation, ease of fiber handling, and long-term reliability in a compact package. Gemfire's athermalisation technology simplifies implementation of AWG multiplexers and demultiplexers by DWDM network providers.
