摘要：

Regenerated fibre Bragg gratings (RFBG) are obtained by heating an original seed grating until its reflection practically vanishes, which is followed by the growth of a new reflection band. Advantages of RFBG for sensing purposes are the longer lifetime and higher thermal stability at higher temperatures, as they have been observed to survive temperatures in the range 1300-1500 degrees C. The thermal stability of the RFBG permits several applications not attained by standard Bragg gratings. (C) 2014 The Authors. Published by Elsevier B.V.
