<p>Abstract — High transmission losses are the key problem that limits the performances of visible light communication (VLC) system that work on wavelength division multiplexing (WDM) technology.<br>
In order to overcome this problem, we propose a novel design for a 1×4 optical demultiplexer based<br>
on the multimode interference (MMI) in slot-waveguide structures that operates at 547 nm, 559 nm,<br>
566 nm and 584 nm. Gallium-nitride (GaN) and silicon-oxide (SiO2) were found to be excellent<br>
materials for the slot waveguide structures. Simulation results show that the proposed device can<br>
transmit 4-channels that work in the visible light range with a low transmission loss of 0.983-1.423 dB, crosstalk of 13.8-18.3 dB and bandwidth of 1.8-3.2 nm. Thus, this device can be very useful in visible<br>
light networking system that works on WDM technology.</p>
