Paper Abstract

We have successfully created Chemical Composition Gratings (CCGs) into two different types of optical fiber: standard telecommunications Germanium doped fibers and photosensitive Germanium/Boron co-doped fibers. We have performed temperature cycles for analyzing the sensing properties and degradation or hysteresis with respect to the CCG sensors. The results show that CCG sensors based on Germanium/Boron co-doped photosensitive fiber have an almost linear response and negligible hysteresis effects, with a response of almost 100°C/s.
