Multiplexing (DWDM) system. A grating formed by arrays of waveguides of equal length difference, using the ability to separate waves.

AWG also has high stability and good cost performance, which is very suitable for high-speed and large capacity DWDM system use. AWG device is a planar waveguide device based on optical integration technology. It has the potential advantages of planar waveguide technology. It is suitable for mass production, with good repeatability, small size, good uniformity of insertion loss, and thermal stability up to 0 after temperature control.


Application

This device combines the light in multiple channels into a single optical fiber at the DWDM transmission end and separate the light at the DWDM receiving end, so as to improve the transmission efficiency of the optical fiber network and reduce the construction cost of the optical network.
