Abstract

High transmission losses are the key problems that limit the performances of visible light communication (VLC) systems that work on wavelength division multiplexing technology. In order to overcome this problem, we propose a novel design for a 1×3 optical demultiplexer based on photonic crystal fiber (PCF) structure that operates at 450 nm, 550 nm, 650 nm. The new design is based on replacing some air-holes zones with silicon nitride material along the PCF axis with optimization of the PCF size. Numerical investigations were carried out on the geometrical parameters by using a beam propagation method. Simulation results show that the proposed device can transmit 3-channel that works in the visible range with low crosstalk ((-18.63)-(-21.24) dB) and bandwidth (5.79-18.63nm). Thus, this device can be very useful in VLC networking systems that work in wavelength division multiplexing technology for increasing VLC speed.
