【Abstract】 A curved fiber taper temperature sensing structure is proposed based on the simple melting pull taper technology. The length of single-mode optical fiber taper is 1.5mm, and the waist diameter is 25μm. The waist diameter of the optical fiber taper coating with polydimethylsiloxane is 100μm. The experimental results presents the temperature sensitivity of the curved fiber taper is-191.41pm/℃. In addition, polydimethylsiloxane has a good hydrophobicity, the proposed sensor can effectively avoid the humidity crosstalk in temperature measurement. At the same time, the preparation process is simple, low cost, high sensitivity, so the proposed fiber sensor has important application prospects in industrial automation, aerospace, biomedicine and other fields.更多还原
