  "abstract": "<p>Abstract &mdash; 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>\nIn order to overcome this problem, we propose a novel design for a 1&times;4 optical demultiplexer based<br>\non the multimode interference (MMI) in slot-waveguide structures that operates at 547 nm, 559 nm,<br>\n566 nm and 584 nm. Gallium-nitride (GaN) and silicon-oxide (SiO2) were found to be excellent<br>\nmaterials for the slot waveguide structures. Simulation results show that the proposed device can<br>\ntransmit 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>\nlight networking system that works on WDM technology.</p>",
