主　　题：Fabry-Perot interferometer fiber Bragg grating fiber optics sensors 

摘      要：A probe-shaped sensor for simultaneous temperature and pressure measurement was reported in this *** effective length of the sensor was〜2 mm,consisting of a fiber Bragg grating(FBG)and a Fabry-Perot interferometer(FPI)with a nano silica *** response sensitivities of the sensor for pressure and temperature were measured as-0.98 nm/MPa and 11.10pm/℃,*** sensor had an extremely low cross-sensitivity between pressure and temperature,which provided a significant potential in dual-parameter sensing.
