## Abstract A novel structure of arrayedβwaveguide grating (AWG) multiplexers with a gradedβindex freeβpropagation region (FPR) used to increase the wavelength pass band is presented. The 1βdB and 3βdB wavelength pass bands increase with the increase of the gradedβindex FPR length. Flat and broaden
A 17 Γ 17 polymer arrayed waveguide grating (AWG) multiplexer with flat spectral response have been designed and fabricated by using FPE polymer materials. The measured results are as: the center wavelength is 1550.83 nm, wavelength channel spacing is 0.8 nm, 3-dB bandwidth is about 0.476 nm, insert
