Rayleigh scattering losses
WebMay 7, 2024 · Scattering losses exist in optical fibers because of microscopic variations in the material density and composition. As glass is composed of randomly connected network of molecules and several oxides (e.g. SiO 2, GeO 2 and P 2 O 5), these are the major cause of compositional structure fluctuation.Three different scattering processes may take place … WebRayleigh scattering is the dominant reason for propagation losses in optical glass fibers (particularly single-mode fibers) at shorter wavelengths, e.g. in the visible and ultraviolet spectral range. Even for perfect glass quality, scattering occurs at the density fluctuations in the glass, which are to some extent unavoidable.
