Abstract :
We report the analysis and measurement on the residual stress in various types of optical fiber preforms to investigate stress variation due to dopant type, their distribution in the cores and post mechanical processes such as preform elongation and over jacketing. To analyze the preform residual stress, an automated residual stress measurement system was also developed based on modified polariscope
