Abstract

Refractive index change in the core of optical fibers by CO2 laser irradiation was measured by using a long period fiber grating (LPG) pair. Effect of drawing force applied to the optical fibers during drawing process on the refractive index change upon the CO2 laser irradiation was investigated. The refractive index was found to decrease linearly with the drawing force and it was due to the relaxation of the residual stress. Effect of the CO2 laser output power on the residual stress relaxation and the fiber elongation was also studied.
