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. © 2004 Wiley Periodicals, Inc.

## Abstract An efficient technique is proposed to flatten the spectral response of an arrayed waveguide grating (AWG) multiplexer. By subtracting an increment from the length difference of odd arrayed waveguides and by adding the same increment to that of even arrayed waveguides, a boxlike spectral

A 17 Â 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
