Generation of ultra violet signal from visible light using photonic crystal fiber: A realization of PCF based UV torch

Though photonic crystal fiber has been exhibiting an exhilarating application since a couple decades, the current communication divulges an another noteworthy upshot vis-a-vis Ultra Violet (UV) signal from Visible light. The photonic crystal fiber is taken as square type silicon based photonic crystal, where nature, position and configuration are mainstay of this research work. The principle of investigation of present study is based on the distribution of electric field in the said suggested fiber in such way that emerging signal from such fiber lies with the range of UV signal. Finally the proposed device acts as fiber based torch light, which could be used for UV applications.
