Abstract

Optical sensors exist in various forms and one of them is Fiber Bragg Gratings (FBG). Performance evaluation was simulated for FBG sensing. The simulation involves different grating profiles tested with complete optical sensing system. The system involves a broadband light source, FBG of various profiles and optical spectrum analyzer for data interpretation. Different profile of gratings imprinted on an FBG outputs wavelength spectra and simulated results satisfy this theory obtained from literatures. Temperature sensing was also simulated for the FBG at various temperature ranges that suit different industrial demands. At low temperatures FBG does give noticeable sensing capabilities. When reaching 400°C and above, the FBG was still capable of providing response, however when in real environments the fiber may suffer from thermal damage. FBG performance when integrated within a system with long distances of fibers were also simulated. Power attenuation was noticed at the reflectivity spectra.
