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 response can be obtained. The simulated result for a 17 × 17 polymer AWG shows that the boxlike spectral response has a 3‐dB bandwidth of 0.49 nm, and the crosstalk is about or less than −28 dB for every output channel. © 2006 Wiley Periodicals, Inc.
