WebMar 19, 2024 · Rayleigh Scattering • Rayleigh scattering , named after the British physicist Lord Rayleigh. • Rayleigh scattering occurs when the size of the particle responsible for the scattering event is much smaller than the wavelength of the incident light. • wave length dependant, favoring short wavelengths, and is responsible for our sky appearing blue. WebLight scattering in such a medium is known as Rayleigh scattering The scattering cross section varies as λ-4 and is dominant at short wavelengths. The intrinsic loss of silica fibers from Rayleigh scattering can be written as. α R = C/λ 4 where the constant C is in the range 0.7-0.9 (dB/km)-μm 4 depending on the constituents of the fiber core.

WebRayleigh scattering loss (RSL) is the major contributor to optical fiber’s attenuation. Hence prediction of its value is very important from designer’s perspective. In literature, there are few reports on RSL models, but those mainly consider step-index fiber profiles. http://plaza.ufl.edu/dwhahn/Rayleigh%20and%20Mie%20Light%20Scattering.pdf
