Abstract:

A simple, highly sensitive fiber Fabry-Perot interference sensor based on polydimethylsiloxane (PDMS) is proposed and demonstrated for simultaneous measurement of gas pressure and temperature. The sensor is fabricated by fusion splicing a short segment of hollow capillary tube to a standard single mode fiber and injecting PDMS in sections into capillary tube, then three reflecting surfaces are formed. Experimental results show that sensitivities of temperature and gas pressure are 2.62 nm/°C and 20.63 nm/MPa, respectively. The proposed sensor has advantages of compact size, low cost, robust structure, easy fabrication, and it is applicable to real sensing application.
