Abstract
The advance progress of the visible light communication field requires new and powerful components that enable high speed light transmission with low losses. Therefore, we propose a novel design for a × 8 green light power splitter based on the multimode interference coupler in a gallium-nitride- silicon-oxide slot waveguide structure. Simulation results show that after a propagation length of 16.55μ text{m} the energy of the green light signal (536 nm) is split into eight output beams with equal energy and low transmission losses of 0.11 dB. In addition, the splitter operates in the visible light spectrum from 460 to 670 nm. Therefore, this splitter can increase performance in network communication system that work in the visible light range.
