Abstract

One of the main obstacles that limited the performances in visible light networking system is the ability to transmit high data communication rate. In order to overcome this obstacle, we propose a novel design for an RGB demultiplexer based on silicon-nitride (Si₃N₄) multicore photonic crystal fiber (PCF) structure. The new design is based on replacing several air-holes zones with Si₃N₄ rods along the fiber length that enable the controlling of the coupling length size between neighboring cores. The locations of the Si₃N₄ rods and the geometrical parameters of the PCF were analyzed and simulated utilizing the beam propagation method (BPM) combined with Matlab codes. Results show that RGB operated wavelengths can be demultiplexed after light propagation of 5.5 mm with an excellent crosstalk of −20.766 to −23.95 dB and a large bandwidth of 5.9–16.3 nm.
