A method for designing an arrayed waveguide grating that includes input and output couplers, input and output slabs, and a plurality of arms connecting the input and output slabs includes steps of determining a desired amplitude response for the arrayed waveguide grating. A desired dispersion response for the arrayed waveguide grating is determined. Input and output couplers are designed to produce the desired amplitude response. The lengths of the arms of the arrayed waveguide grating are perturbed to produce a flat or linear dispersion. In addition, the polarity of a group delay, dispersion and dispersion slope response of an arrayed waveguide grating can also be changed by adjusting Individual lengths of the waveguide arms. The group delay, dispersion and dispersion slope of a multiplexer and a demultiplexer can be matched to substantially cancel.
