Refractive Index, Phase Velocity, Group Velocity, and Dispersion Parameter The index of refraction of a dielectric as a function of wavelength may be accu- rately represented using a Sellmeier equation of the form n 2 = A + ± k G k λ 2 λ 2 - λ 2 k , where A , λ k , and G k are called the Sellmeier coefficients. The quantities λ k and G k represent resonant wavelengths and oscillator strengths respectively. For fused quartz, A =1 , λ 1 =68 . 4 nm , G 1 =0 . 69617, λ 2 = 116 . 2 nm , G 2 =0 . 40794, λ 3 = 9896 . 2 nm , G 3 =0 . 89748. Calculate, showing all work, the refractive index n

Unformatted text preview: v p in m/sec , the group velocity index N g , the group velocity v g in m/sec , and the disperi-son parameter D in ps/km/nm for this material at a freespace wavelength of 1 . 5 μm . Express refractive indices accurately to ± . 00001, velocities accurately to within ±ve sig-ni±cant ±gures, and the dispersion parameter accurately to four signi±cant ±gures. Put your ±nal answers in the spaces provided below. n = v p = m/sec N g = v g = m/sec D = ps/km/nm...
