Analysis of waveguide silica glasses using Raman microscopy

“…The Raman spectra of vitreous silica [22,24,25] and the binary silica glasses GeSG, BSG and PSG [22][23][24]27,[39][40][41] have been reported previously in the literature. The assignments of the spectral features that appear in the spectral region from 740 cm À1 to 1270 cm À1 on the basis of this previous work are given in Table 2.…”

“…Raman spectroscopy has been used extensively to investigate silica glasses [20][21][22][23][24][25][26][27][28][29]. The excitation wavelengths available in modern Raman instrumentation, which range Table 1 Techniques reported as being used to measure the phosphorous and/or boron content in BPSG waveguide cladding glass, or the germanium content of germanium-doped silica waveguide core glass, or both Technique Criterion Relative cost Refs.…”
