Abstract :
We proposed and experimentally demonstrated five kinds of gas pressure sensors based on in-fiber devices, including a long period fiber grating written in air-core bandgap fiber, a fiber-tip air bubble, a polymer-capped Fabry-Perot interferometer, an inflated long period fiber grating and a twin-core fiber-based Mach-Zehnder interferometer, which exhibited a sensitivity of 137, 1036, 1130, 1680, 9600 pm/MPa, respectively.
