Thermally insensitive pressure measurements up to 300 degree C using fiber bragg gratings written onto side hole single mode fiber

Tsutomu Yamate; Rogerio Tadeu Ramos; Robert J. Schroeder; Eric Udd

A thermally insensitive pressure measurement up to 300 degree C was demonstrated utilizing fiber Bragg gratings written onto a side-hole single mode fiber. The resulting temperature sensitivity is about 300 times lower than normal FBGs.
