Raman Investigation of Optical Fibers under High Tensile Stress.

Abstract

Raman spectra have been obtained from fused silica optical fibers under tensile stresses from 0 to 3.3 GPa (33 kbar). Reversible intensity increases, relative to the principal Raman maximum at 490 per cubic meter were observed for the defect peak at 490 per cubic meter and for shoulders near 350-375 per cubic meter and 115 per cubic meter. Application of tensile stress to fused silica appears to produce changes in the stretched Si-O defect sites, as well as changes in the main network structure. (Author)
