he objective of this work is to develop and optimize the Fiber Bragg (FBG) grating based surface plasmon resonance (SPR)
sensor for monitoring the hazardous toxic chemicals and gases in underground mines or any industrial area. A fully cladded
telecommunication standard FBG is proposed to develop to produce surface plasmon resonance. A thin few nm gold/silver
film (subject to optimization) is proposed to apply over the FBG sensing head using e-beam deposition method. Sensitivity
enhancement of the sensor will be done by adding a composite nanostructured graphene oxide (GO) sensing layer using the spin
coating method. Both sensor configurations supposed to demonstrate high responsiveness towards the changes in resonance
wavelength. The GO enhanced sensor may show increased sensitivity of many fold compared to the gold coated traditional fibre
optic sensor. Our work is focused on to optimize GO, multilayer structure and to develop fibre coating techniques that will serve
well for sensitive and multifunctional detection of hazardous chemicals. This research proposal shows great potential towards
future development of optical fiber sensors using readily available components such as Bragg gratings as highly sensitive
chemical sensors in areas such as environmental sensing.
