Abstract: Arrayed waveguide gratings (AWGs) are important components in coarse wavelength divisional multiplexing (CWDM) and dense wavelength division multiplexing (DWDM). However, the waveguides forming the array must be separated by a distance large enough to suppress parasitic coupling between the adjacent waveguides and thus limiting reductions in device footprint and insertion loss between the input/output coupler regions and the central region comprising the arrayed waveguides. The inventors have established a design methodology allowing the waveguide separation to be reduced whilst limiting cross-coupling thereby allowing for reduced footprints and insertion loss.
