理工学院光电工程系本科生欧阳腾辉、林丽敏同学，在关贺元博士、余健辉副教授的指导下，在光学工程领域国际权威期刊“Optics Express”（二区）发表了科研论文：“Enhanced optical sensitivity of molybdenum diselenide (MoSe2) coated side polished fiber for humidity sensing, Optics Express, 2017, 25(9): 9823
Tungsten disulfide (WS2) sheet wrapped on the tapered region of micro fiber (MF) and its humidity sensing are proposed and demonstrated. WS2 coated MF (WS2CMF) is demonstrated to enhance the interaction and contact area between WS2 and the strong evanescent field of optical fiber. An enhancement in sensitivity (0.196 dB/%RH) of the WS2CMF is achieved in a RH range from 37%RH to 90%RH. Furthermore, the proposed WS2CMF shows a good repeatability from 40%RH to 75%RH and a rapid response to periodic breath stimulus. This WS2CMF holds great potential in all optical sensing networks owing to the advantages of high sensitivity, compact size and low cost.
