In this paper we present design and modeling of insertion losses in arrayed waveguide gratings (AWG) demultiplexer without and with
Multi mode interference (MMI) couplers. Using spatial Fourier transform approximation, we show that the total insertion loss with MMI
couplers is almost four times greater than that without MMI couplers. Also we show that most of the loss comes from the spatial diffraction.
