Abstract

A hybrid fiber grating-based temperature sensor with simple demodulation scheme has been constructed. Temperature variation of 1 degree C could be linearly resolved in a 40 degree C range by directly measuring the transmission power through a long period fiber grating with a bandwidth of 6.5nm.
