摘要：
In this letter, the periodic focusing effect of graded-index multimode fibers is used to improve the performance of fiber-optic Fabry-Perot (FFP) sensors. The maximum fringe contrast of the reflective spectrum of the FFP sensor in air is > 32 dB. By detecting the fringe contrast variation and wavelength shift of the reflective spectrum, such an FFP sensor is used to measure the refractive index and temperature with sensitivities of similar to 45.05 dB/RIU and 11.5 pm/degrees C, respectively. It is also verified by the experiment that the simultaneous measurement of refractive index and temperature can be realized.
