In the present paper, we will investigate theoretically the basic design parameters of silica-based arrayed waveguide grating (AWG) in the C-band’s spectral range (from 1.528 to 1.56 μm). We have demonstrated theoretically that the minimum the diffraction order m, the maximum the number of the input/output wavelength channels, and the maximum the number of the arrayed waveguides. Also, we have investigated the optimization design parameters of AWG for C-band applications.
Key words: Silica-based AWG, wavelength multiplexer, wavelength demultiplexer, dense wavelength division multiplexing (DWDM), free spectral range (FSR).
