Abstract
To overcome this problem, we propose a novel design for a 1â¯Ãâ¯4 optical demultiplexer based on the multimode interference in a slot-waveguide structure that operates at 547â¯nm, 559â¯nm, 566â¯nm, and 584â¯nm. Gallium nitride and silicon oxide were found to be excellent materials for the slot-waveguide structure. Simulation results showed that the proposed device can transmit four channels that work in the visible light range with a low transmission loss of 0.983-1.423â¯dB, crosstalk of 13.8-18.3â¯dB, and bandwidth of 1.8-3.2â¯nm. Thus, this device can be very useful in visible light networking systems, which work on the WDM technology.
