“…The developed LPG device displays significant potential as a highly sensitive and cost-effective pressure sensor with pressure sensitivity of about 5.1 pm/bar, which is more than an order of magnitude more sensitive to pressure changes than a standard FBG [4]. At the same time, the temperature drift of the resonance wavelength in our gratings is still smaller than that reported for other gratings [6].…”

Abstract-The method and the required installations for fabricating tapered long-period fiber gratings can be simpler than that of standard fiber Bragg gratings, and the fabrication process is faster. To our knowledge, the 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 setup, and the preliminary results are presented and discussed. The pressure sensitivity of the sensor is as high as 5.1 pm/bar. Index Terms-Fiber-optic sensors, long-period fiber gratings, pressure calibration and measurement, step index fiber, tapered long-period gratings (TLPGs), temperature.

“…3, shifts under the influence of external parameters, and this is the foundation of the metrological applications of LPGs. Such a shift has already been determined in the case of temperature and strain; consequently, both features have been exploited in the development of novel fiber-optic sensors [4], [6].…”

“…To date, various types of fiber optic temperature sensors have been reported in the literatures and they are mostly based on fiber interferometric [Choi et al, 2008] and fiber Bragg grating (FBG) [Han et al, 2004]. However, the first type of sensors are rather expensive to produce and complicated to implement on-site [Golnabi, 2000].…”

“…In principle, fluorescence is induced by pump power at a certain wavelength that is suitable for the doped ions, and a straightforward detection procedure is simply needed. Additional advantage of such rare-earth-doped fiber sensors is that they are compatible with a wide range of existing fiber-optic multiplexing schemes that can simultaneously detect multiple physical parameters [3,4].…”
