## Abstract A novel structure of arrayed‐waveguide grating (AWG) multiplexers with a graded‐index free‐propagation region (FPR) used to increase the wavelength pass band is presented. The 1‐dB and 3‐dB wavelength pass bands increase with the increase of the graded‐index FPR length. Flat and broaden
