Abstract

In this work, Hollow-core Optical Fibers (HOF) functionalized with Single Walled Carbon NanoTubes (SWCNTs) are proposed for volatile organic compounds (VOCs) detection. The sensing probe is composed by a piece of HOF with a termination coated and partially filled by SWCNTs. The infiltration of the SWCNTs inside the HOF holes has been accomplished by means of the Langmuir-Blodgett technique. Reflectance and far field transmission characteristics have been carried out within the HOF bandwidth. Finally the sensing capability of the proposed sensors has been investigated by exposure in a proper designed test chamber to traces of toluene. The experimental results obtained demonstrate the success of the SWCNTs partial filling within the HOF holes and the sensor capability to perform VOCs detection with a good sensitivity and fast response times.
