摘要：
A hybrid optical fiber structure of two cascading long-period fiber gratings (LPFGs), respectively, inscribed on a segment of few-mode fiber (FMF) and single-mode fiber (SMF), is proposed and experimentally demonstrated. This structure could be used for simultaneous measurement of strain and temperature. The FMF-LPFG exhibits an opposite temperature response and higher strain sensitivity compared to that of the SMF-LPFG, which can improve the measurement resolutions. Experimentally, the strain and temperature sensitivities of the proposed sensor are -2.9 pm/mu epsilon and -17.6 pm/degrees C, respectively, for the FMF-LPFG; for the SMF-LPFG, these are -1.47 pm/mu epsilon and 46.4 pm/degrees C, respectively. The maximum errors are +/- 7.98 mu epsilon and +/- 0.54 degrees C for strain and temperature, respectively. (C) 2014 Optical Society of America
