Athermalized Arrayed-waveguide grating (AWG) wavelength multi / demultiplexer
Athermal AWG

AWG (Arrayed Waveguide Grating) is a multi-port optical filter that has a large number of waveguides in an array. Due to the interference of the multi-beams passed through these waveguides, an extremely high extinction ratio can be realized like a Bragg Grating.
On the other hand, because our AWG is made with PLC technology, it has high reliability and satisfies Telcordia GR-1209 and GR-1221.
Therefore the AWG is widely used in large capacity optical transmission systems as an optical multi / demultiplexer that bundles and separates optical signals of different wavelength.
In a lasted DWDM (Dense Wavelength Divission Multiplexing) system, each component must have high optical wavelength stability.
NTT Electronics's athermal AWG achieves high optical wavelength stability in a very compact size without a temperature controller.
