Abstract

This experimental work presented the reduced graphene oxide (rGO) immobilized etched fiber Bragg grating (eFBG) sensor to improve refractometric sensitivity. The effectiveness of the proposed sensor is evaluated with cigarette smoke as well as incense smoke by monitoring the shift in the resonant peak of the reflection spectra of the sensor with the interrogator. An increase in the interaction of the evanescent field adsorbing with the smoke caused by the rGO layer increases the sensing performance. Raman spectroscopy, XRD, and field emission scanning electron microscope are used for characterization of the sensor.
