Rayleigh scattering in fiber formula
WebModern Rayleigh scattering calculations have tradi-tionally been made by starting with those presented by Penndorf (1957). In Penndorf’s paper, the refractive in-dex of air was calculated using the equation of Edle´n (1953): (n 2 1) 3 108 s 2 949 810 25 540 5 6432.8 11, (1) 146 2 l22 41 2 l22 where ns is the refractive index of air andlis ... WebRayleigh scattering attributed to the density fluctuation of silica glass is considered as the intrinsic origin of optical loss in glass fiber. Therefore, minimizing the density fluctuation is key to improving the information and telecommunications networks. In this study, classical molecular dynamics (MD) simulations were employed to theoretically examine the …
