Title : RGB port demultiplexer using polycarbonate core polymer optical fiber technolgy

Abstract:

Wavelength division multiplexing (WDM) is a great solution for increasing data bitrate communication of multicore polymer optical fiber (MC-POF) system. However, this solution requires adding more optical devices to the system which can limit its performance. To solve this issue, we propose a new design for an RGB channel based on polycarbonate (PC) MC-POF structure.  The new structure is based on replacing seven air-holes areas with PC layers over the fiber length which enables controlling the light propagation direction between the pc layers. The locations of the PC layers and the key geometrical parameters of the MC-POF were analyzed utilizing the beam propagation method. Results show that an RGB demultiplexer can be obtained over a light propagation of 20 mm with a good crosstalk of -19.436 to -26.474 dB, low losses of 0.901 to 1.246 dB and a large bandwidth of 5.6 to 11.3 nm. By analysis the results, it is clear that the main advance is that the new design does not require additional devices in order to function as RGB demultiplexer. This advance can be utilized to design new and very compact VLC-WDM system that can be used to obtain better performances comparing to VLC-WDM system that used bulk components.
