This kind of 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.
The arrayed waveguide particles used in wavelength division multiplexing (WDM-PON) are also referred to as AWGs.This is a method of using a high-speed transmission of a manual optical transmission product. For the transmission method of large-capacity storage signals such as images, telephones, and data, it is only necessary to divide 16 or 32 members into one line of light at the same time. There are also applications in areas that require long-distance transmission.
