Abstract
Efforts to develop ultralow loss optical fibers typically have concentrated on glasses with IR edges at longer wavelengths than silica. An alternative approach is the development of glasses with significantly lower Rayleigh scattering losses. While it is occasionally noted that certain oxide glasses, such as the aluminosilicates,1 do scatter less light than silica, these differences have been attributed to variations in fictive temperature, compressibility, and refractive index. Recently, it has been suggested2 that glass structure may have a significant impact on Rayleigh scattering and, therefore, that there may be glasses that have significantly less Rayleigh scattering than silica. Using simple aluminosilicate glasses melted via standard glass forming techniques, we confirmed that Rayleigh scattering due to density fluctuations is a predictable function of intrinsic glass structure. A number of these glasses scatter less light than silica.
