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 broadened spectral responses are obtained by using this novel structure.
