“…The basic working principle of the side-port MMI demultiplexer is based on the self-imaging effect in the multimode section [14,15], where the input field profile is reproduced in single or multiple images due to phase of guided modes changing at one side of the multimode section at periodic intervals along the propagation direction of the multimode waveguides, as shown in Fig. 1 (c).…”

Based on side-port multimode interference coupler, a novel design of 1.31/1.55-μm wavelength multiplexer/demutiplexer on SOI platform with conventional channel waveguides is proposed and analyzed by using wide-angle beam propagation method. With a 25.9μm long ultra-short MMI section, nearly an order of magnitude shorter than that of the previously reported 1.31/1.55-μm wavelength MMI splitters on SOI, simulation results exhibit contrasts of 28dB and 25dB at wavelength 1.31 and 1.55 μm, respectively, and the insertion losses are both below 0.55dB. Meanwhile, the analysis shows that the proposed structure has larger fabrication tolerances than restricted MMI based structures and the present design methodology also applies to split other wavelengths and in different material platforms, such as InP, GaAs and PLC guides, etc.

“…(2), a restricted MMI coupler can be three times shorter than a general MMI coupler. A proposed 1 ϫ 2 restricted MMI structure [8] has been used to separate the two wavelengths 1 and 2 . The wavelength separation can be performed if the length L MMI of the restricted MMI coupler has been designed so that it is equal to an even number of L ,1 and to an odd number of L ,2 , such that…”

“…Several works have been performed to design an MMI-based demultiplexer in order to split the two telecommunication wavelengths, using the restricted interference mechanism [18][19][20][21], or an inverse design algorithm [22]. To the best of our knowledge, there has not been any demonstration of such components for NIR/MIR wavelengths.…”

Based on restricted interferences mechanism in a 1x2 MMI beam splitter, we theoretically investigate and experimentally demonstrate an ultra-compact MMI-based demultiplexer for the NIR/MIR wavelengths of 1.55 μm and 2 μm. The device is fabricated on 340 nm SOI platform, with a footprint of 293x6 μm 2 . It exhibits extremely low insertion losses of 0.14 dB and 1.2 dB at the wavelengths of 1.55 μm and 2 μm, respectively, with contrasts of approximately 20 dB for both wavelengths, and a cross-talk of 18.83 dB.
