Abstract

The method and the required installations for fabricating tapered long-period fiber gratings can be simpler than that of the standard fiber Bragg gratings, and the fabrication process is faster. To our knowledge the fiber-optic tapered long-period fiber grating pressure sensor is presented here for the first time. In this paper the fabrication method for tapered long-period fiber gratings, the sensing principle, the sensor structure, the measurement set-up and the preliminary results are presented and discussed. The pressure sensitivity of the sensor is as high as 5.1 pm/bar
