Enclosure type AWG

Description and Application

       Array Waveguide Gratings (AWG) are commonly used in WDM systems as optical WDM multiplexers, which are capable of compounding many wavelengths of light into a single fiber at the input end with only negligible signal crosstalk, and then separating different wavelengths of light into different output ports at the output end, thus improving the propagation efficiency of the fiber optic network. Array waveguide grating components include input waveguide, input coupler, array waveguide, output coupler, and output waveguide. The input/output waveguide ports are arranged on the Roland circumference, and the array waveguide ports are arranged on the circumference of twice the diameter. The array waveguide is similar to a concave grating, and the light is reflected and diffracted by the array waveguide, with different diffraction angles for different wavelengths, so that it is received by different output waveguides to achieve the purpose of wave decomposition multiplexing.
