Graphene oxide coated long period grating for optical sensing purposes. Journal of Physics: Conference Series, 1151(1), 012022.. doi: 10.1088/1742-6596/1151/1/012022 ISSN 1742-6588


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.
