Athermal AWGAWG Multi / Demultiplexer
AWG (Arrayed Waveguide Grating) is a multi-port wavelength 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 Innovative Devices' athermal AWG achieves high optical wavelength stability in a very compact size without a temperature controller.

Thermal AWGAWG Multi / Demultiplexer
AWG (Arrayed Waveguide Grating) wavelength multi / demultiplexer combines and splits optical signals of different wavelengths for use in WDM system. It consists of temperature control for the precise wavelength stability of the filter.
The heart of the device, the AWG, has a number of arrayed channel waveguides that offers high wavelength resolution, thus attaining narrow wavelength channel spacings such as 0.8nm in ITU channel allocation. The device offers long-term reliability because it employs the PLC technology, which passes GR-1209-CORE and GR-1221-CORE.
FEATURES
- Dence and accurate channel spacing
- Large number of channel up to 128
- Polarization insensitive
