RGB multiplexer using polycarbonate MC-POF technology

One of the common methods to increase data bitrate using visible light communication (VLC) fibers system is to use wavelength division multiplexing (WDM). However, the implementation of WDM requires additional components and more energy consumption which can limit the system performances. To overcome these issues, we propose a new method for designing an RGB multiplexer based on multicore polymer optical fiber (MC-POF). The new design is based on replacing seven air-holes areas with polycarbonate (PC) layers along the fiber length. The PC layer length sizes are suitable to the light coupling of the operating wavelengths which allows us to control the light switching between closer PC layers and to obtain an RGB multiplexer device without adding more devices. Results show that after a 20 mm light propagation the PC MC-POF RGB multiplexer can be obtained with a low power loss of 0.6 to 1.02 dB, large bandwidth of 7.3 to 28.4 nm and good isolation between the transmission of the input RGB channels.
