A tapered silica optical fiber (SOF) coated with graphene oxide is proposed and demonstrated as a humidity sensor. In order to reduce the diameter of the optical fiber from 125 µm to 26.9 µm as the sensing region, the flame-brushing technique was used to taper the fiber with the tapering length is a...
