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 planar processed
silica-on-silicon chips comprise arrayed channel waveguides to
separate or combine multiple wavelengths. Athermal AWG s allow
multiplexing and demultiplexing of DWDM signals over a wide
operating temperature range, without the need for heater drive and
monitoring electronics.
These AWG offer low insertion loss, excellent channel isolation,
ease of fiber handling, and long-term reliability in a compact
package. Unifiber’s athermalization technology simplifies
deployment of AWG multiplexers/demultiplexers by DWDM network
providers.
