title: Liquid-filled photonic-crystal-fiber-based multimodal interferometer for simultaneous measurement of temperature and force.
abstract: In this paper, a multimodal interferometer based on the liquid-filled photonic crystal fiber (PCF) has been proposed and experimentally demonstrated for simultaneous measurement of temperature and force. Experimental results show that different spectral minima have distinctive sensitivities to the temperature and force. The proposed interferometer shows the temperature sensitivities of -9.214 nm/°C, -24.757 nm/°C, and -12.543/°C and the force sensitivities of 0 nm/N, 4.978 nm/N, and 0 nm/N, respectively, for the three selected spectral minima. The sensing matrices are thus established and simultaneous measurement of temperature and force has been experimentally demonstrated. The proposed liquid-filled PCF-based multimodal interferometer would find potential applications in multiple-parameter sensing owing to its high sensitivity, compactness, ease of fabrication, and low cost.
