Abstract

The generation of signal of white LED is realised in this research with the help of hybrid photonic structure, where hybrid structure deals with the combination of four plasmonic based photonic crystal fiber. Here the four square lattice photonic crystal fibers are designed in such way that first three fibers produce red, blue and green signals and fourth one will combine all three signals (R-B-G), which gives the signal of white LED. The principle of generation of these signals relies on the field distribution in the proposed photonic crystal fiber and filtering application. Aside these, different transmission spectrum are shown for the sake of confirmation of the generation of R-B-G as well as white signal. The simulation results are carried out with the help of plane wave expansion techniques. Moreover the present research indicates the throughput efficiency of each fiber though numerical expression. It is also obtained that the fiber 1, 2, 3 and 4 transmits signal (bandwidth) of 79.2 THz, 46.6 THz, 80.85 THz, and 180.8 THz corresponding to the channel capacity of 80 THz, 47.1 THz, 81.3 THz, and 182.6 THz respectively. The overall efficiency of the fiber is more than 99%. Finally, it is envisaged that the proposed hybrid photonic crystal fiber system is an equivalent to the white LED, because the proposed system generates the signal of 395 nm to 520 nm which is the spectrum of white LED.
