Current PhD StudentTheoretical investigation of optical fibre surface plasmon resonance palladium-based hydrogen sensors
The aim of this research project is to develop a theoretical model that describes the operation and optimization of an optical fibre based sensing device for the purpose of detecting hydrogen gas. We propose a novel step-index multimode optical fibre surface plasmon resonance sensing device. Throughout this research, various materials, alloys, nanoparticles, and nanocomposites were investigated for use in the multilayer stack sensing structure. Multi-channel functionality was implemented through wavelength division multiplexing. Finally, the first evidence of surface plasmon and waveguide mode resonance stimulated at equal wavelengths is demonstrated using a single multilayer sensing structure.
