Abstract
The paper presents a FPI sensor by splicing a photonic crystal fiber (PCF) to a well-cleaved single-mode fiber (SMF) and a multimode fiber (MMF), preparing a SMF–PCF–MMF structure, and the section of PCF was the cavity. Temperature and NaCl solution concentration responses were investigated experimentally. The temperature sensitivity is ∼12.3 pm/°C and concentration sensitivity is ∼0.01 dB/%. The proposed sensor could offer such features as low cross-sensitivity, good temperature stability, temperature and concentration linearity are both over 0.996, making it attractive for liquid concentration and temperature measurement.
