One of the main obstacles that limited the performances in visible light networking system is the ability to transmit high data communication rate. Wavelength division multiplexing (WDM) is a good solution for increasing data bitrate communication of photonic crystal fiber (PCF) and multicore polymer optical fiber (MC-POF) based visible light communication (VLC) system. In order to overcome this obstacle, we propose two new designs for an RGB demultiplexer, one is based on silicon-nitride (Si3N4) multicore PCF structure and the second is based on polycarbonate (PC) MC-POF structure. The new design is based on replacing several air-holes areas with Si3N4 rods in PCF and PC rods in POF over the fiber length which enables controlling the light propagation direction between the core layers. The locations of the Si3N4 / PC rods and the key geometrical parameters of the device were optimized and analyzed 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 for PCF and 20 mm for POF with an excellent crosstalk of -19.436 to - 26.474 dB and a large bandwidth of 5.6 to 16.3 nm.
