The sellmeier equation
WebNov 1, 2024 · The Sellmeier equation is a common model for describing the wavelength-dependent refractive index of glasses and crystals. In the Sellmeier equation the refractive index of materials can be described in a wide range of wavelengths with only a few constants which are known as Sellmeier coefficients [1]. Sellmeier equation is extremely … WebFor the calculation of the wavelength dependent refractive index we apply the three term Sellmeier equation (Matthijsse et al. 2005): X3 ai k2 n2 1 ¼ 2 2 : ð9Þ i¼1 k ki By assuming that the fiber is pure silica glass (SiO2 ) doped only with Ge, we may use the fallowing relations for the Sellmeier coefficients (Matthijsse et al. 2005): ai ...
