A Novel Temperature Sensor Based on a Long Period Fiber Grating With a Unique Double-cladding Layer Structure

A novel temperature sensor based on long period fiber gratings (LPGs) with a unique double-cladding layer structure, which increases the temperature sensitivity, is presented in this paper. Cladding layer of the LPG is etched properly, and then packaged in stainless tube filled with index-matching fluid of relatively low thermal coefficient. It is observed in experiments that sensitivity of l.lnm/0C for a temperature range of 15℃ achieved for such a LPG sensor, which is about 100 times larger than that of sensors made of traditional fiber Bragg grating. It also has a linearity of 99.89% and small size of Φ:lmm*L:50mm, which shows a good promise for future application.
