Abstract
We propose and experimentally demonstrate a simple fabrication and high sensitivity Fabry–Perot interferometer polymer (FPIP)-coated temperature sensor based on Fresnel reflection. The single mode fiber end-face was coated with a polycarbonate (PC) or poly(methyl methacrylate) (PMMA) thermosensitive polymer. The experimental results indicate that the FPIP sensor coated with PMMA exhibits the average temperature sensitivities of 312.5 and 257.0 pm °C−1 for the thicknesses of 5.2 and 6.5 μm, respectively, in the temperature range of 26 °C–80 °C. Meanwhile, the FPIP sensor coated with PC exhibits the average temperature sensitivities of 245.4 and 103.6 pm °C−1 for the thicknesses of 4.9 and 9.9 μm, respectively, in the temperature range of 26 °C–140 °C. The FPIP sensor coated with PC indicates a relatively low sensitivity compared to PMMA coated sensor. However, the available operating temperature range for PC sensor is larger than PMMA.
