In this paper, we propose a vacuum ultraviolet (VUV) torch with the help of copper-based plasmonic photonic crystal fibre. The principle of operational mechanism relies on the distribution of electric field in the photonic fibre. The working principle of the torch relies on the generation of vacuum ultraviolet signal with respect to the red signal (input signal). Here, plane wave expansion technique is employed to acquire the electric field distribution in the fibre. Moreover, the output result indicates that suitable combinations of different structure parameters of the plasmonic fibre structure are right candidate to realise VUV torch. Furthermore, the said torch could be used for solving environmental issue because the output (VUV) signal scan breaks CO2 molecules and converts them into the oxygen.
