  • An optical fiber hydrogen sensor using a palladium-coated ball lens 
    Chowdhury, Sahar A.; Correia, Ricardo N.; Francis, Daniel; Brooks, Simon J.; Jones, Benjamin J. S.; Thompson, Alexander W. J.; Hodgkinson, Jane; Tatam, Ralph P. (Institute of Electrical and Electronics Engineers, 2015-06-15)
    A self-referenced optical fiber refractometer using a ball lens as a sensor head has been developed and characterized. A 350-μm ball lens created at the tip of a single mode fiber has been coated with a 40-nm optically ...
  • Refractive index sensitivity of fibre optic long period gratings with SiO2 nanoparticle based mesoporous coatings 
    Korposh, Sergiy; Lee, Seung-Woo; James, Stephen W.; Tatam, Ralph P. (2011-12-31)
    A fibre optic long period grating (LPG) with an nano-assembled mesoporous coating of alternate layers of poly (allylamine hydrochloride) (PAH) and SiO2 nanospheres was used for the development of a fibre-optic refractometer. ...
