Graphene oxide coated long period grating for optical sensing purposes. In: Journal of Physics: Conference Series. Newton Researcher Links Workshop: 2018 Bio-Photonics For Medical Technologies, 23–25 Jul 2018, Malacca, Malaysia. doi: 10.1088/1742-6596/1151/1/012022


In this paper, fabrication and surrounding refractive index response of a graphene oxide (GO) coated long period grating (LPG) is presented. An improved version of the Hummer's method was followed for the synthesis of GO used in this work and GO sheets were immobilized on the LPG fibre surface by using an electrostatic self-assembly technique. In this initial performance evaluation, intensity and wavelength variations of the transmission loss bands of the GO coated LPG were recorded at room temperature and this sensor probe is introduced as a good candidate for the further development of selective biosensors.
