Abstract

In this paper, an external refractive index sensor is presented based on a graphene oxide coated long period grating and based on creating a stable graphene oxide coating on the fibre surface using a drop casting technique. The wavelength shift sensitivity was enhanced by 43% compared to the response of a bare long period grating when used to monitor external refractive index.
