Abstract

The pressure responding theoretical models are got for two intrinsic Fabry-Perot interferometric fiber pressure sensors fabricated by single mode and multimode fibers with different diameters. The pressure response curves are simulated by Matlab programs. The analysis showed that the sensitivity changing situation is different for two structures. The big size structure has a critical point of sensitivity. Higher sensitivity can be got by two structures, but the small size structure is more attractive than the big size structure.
