Highly sensitive long-period fiber grating temperature sensor

A novel technique to increase the temperature sensitivity of LPGs by exploiting the relatively large thermal coefficient of index-matching fluid to induce a large spectral shift of the LPG is reported in this paper. It is shown that the wavelength shift with temperature for such a LPG sensor can be as much as 1,500 times larger than that of sensors made of fiber Bragg gratings. A LPG-based temperature sensor with a resolution of about 0.03 degree(s)C is reported.
