A PROCESS AND SYSTEM FOR MANUFACTURING STABLE FIBER BRAGG GRATINGS (FBGS)

摘要

The invention disclosed relates to a manufacturing process and system to produce high quality Fiber Bragg Gratings by calculating the decay behaviour of the FBGs from their growth and annealing the grown FBG under a temperature for a time decided on the basis of the analysis done on the growth characteristics. This process excludes the need for expensive and time consuming accelerated aging testing experiments. This process also helps in discarding the gratings which may be determined to be unusable based on the writing data without further processing.
