Paper Abstract

Some research results on tunable fiber gratings and their applications are presented in this paper. Dynamic characteristics of thermal tuned FBG by surface coated heater are described. Tuning characteristics and effects of friction in compression tuning packaging are analyzed. Tuning behaviors of LPG in Panda fiber are described and discussed. A pressure sensor by LPG is presented. And demodulation for sensor systems by using tunable FBG is proposed.
