Abstract
Raman spectra have been obtained from fused silica optical fibers under tensile stresses from 0 to 3.3 GPa (33 kbars). Reversible intensity increases, relative to the principal Raman maximum at 440 cm−1, were observed for the defect peak at 490 cm−1 and for shoulders near 350–375 and 115 cm−1. 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.This publication has 11 references indexed in Scilit:
