Abstract

We present a new design for N-channel wavelength division demultiplexer using multistage multimode interference (MMI) structure. First, the general formulation for an N-channel demultiplexer in multimode area has been discussed. In this paper, we proposed a single parameter for designing a demultiplexer with desired wavelengths, number of output channels and channel spacing. Then we simulated an 8-channel wavelength demultiplexer with high quality factor in the telecommunication range. The simulated structure shows 5 nm channel spacing and 2451 average quality factor. The excellent properties of this formulation are the high quality factor and its capability for choosing the desired number of output channels and channel spacing. The beam propagation method is used for simulation of the proposed device.
