Arrayed Waveguide Grating:

i. Arrayed waveguide grating (AWG) is used for demultiplexing. These are based on diffraction principle. The input consists of several channels carrying different wavelengths.

ii. Light propagating in the input waveguides are coupled to the arrayed waveguides after propagating through a free space region (FPR).

iii. …
