Abstract

One important use of molybdenum disulfide (MoS2) could be in making sensing and detection devices with optical chip or fiber. Here, MoS2 nanosheets coated on side-polished optical fiber (SPF) is proposed, which can enhance the localized interaction between evanescent light of fiber core and MoS2 nanosheets, this can motivate greatly sensing and detection performance. Moreover, the MoS2 nanosheet possesses exceedingly high surface/volume ratio. By combining the MoS2 nanosheets and the side-polished fiber, humidity sensing characteristics has been demonstrated. The optical transmitted power (OTP) of the MoS2-based SPF changes with a negative correlation to the variation of relative humidity (RH) in experiments. The OTP changes of the MoS2-based SPF as an exponential function can reach ~13.5dB (~54 fold enhancement) when the RH ranges from 40%RH to 85%RH. Furthermore, experiments on the monitoring of human breath have also been conducted to evaluate the response time (0.85 s) and the recovery time (0.85 s). The performance comparison between this proposed device and the other recent-developed fiber-optic humidity sensing devices in literature illustrates the superiority of the MoS2-based SPF in humidity sensing and monitoring of human breath, which paves a path for the MoS2 nanosheets to integrate in lab-on-fiber sensing and detection devices.
