Abstract: (686 Views)
In this paper, an optical fiber sensor (OFS) based on extrinsic Fabry–Pérot (F-P) interferometry (EFPI) is reported for acoustic waves detection. The sensor diaphragm is made of disulfide molybdenum (MoS2) and graphene oxide (GO) nanosheets. These diaphragms are placed in the end face of single-mode fiber (SMF) optics. Due to the lower Young’s modulus of the MoS2 rather than GO, the fabricated sensor benefits high sensitivity to detect acoustic waves. The results show that the sensitivity of the MoS2-based sensor, ~18.50 rad/Pa, is more than the GO-based sensor (~15.52 rad/Pa).
