This paper analyzed the characteristics of arrayed-wave-guide gratings by using the wave theory. The numerical propagation model and the relationship between the diffraction efficiency and ω 0/d were introduced. The method to design the important structural parameters of the device such as diffraction order, number of arrayed waveguide and focal length was introduced. A 16×0.8?nm AWG multiplexer with a center wavelength 1?550?nm designed as an example was given.
