Abstract

We present a new design of wavelength division demultiplexer based on self-imaging principle in the multimode interference (MMI) structure. We simulated an 8-channel wavelength demultiplexer with high quality factor in the telecommunication range. The structure has been designed with multi-stage multimode interference couplers. The principle of the design of structure can be extended to N-channel wavelength division demultiplexer. To the best of our knowledge, this work presented for the first time in MMI structure with almost 5nm channel spacing and 2451 average quality factor. Output wavelengths that are achieved from the first to the latest outputs are 1545nm, 1564.4nm, 1535nm, 1554.37nm, 1530nm, 1549.9nm, 1540nm, 1559.5nm, respectively. The beam propagation method is used for simulation of this device.
