Group Velocity Dispersion in a Medium Described by the Sellmeier Equation. (a) Derive expressions for the group index N and the group velocity dispersion coefficient D2 for a medium whose refractive index is described by the Sellmeier equation (5.5-28). (b) Use a computer to plot the wavelength dependence of n, N, and D2 for fused silica in the region between 0.25 and 3.5 μm. Make use of the parameters provided in Table 5.5-1 (and Example 5.6-1). Verify the curves provided in Fig. 5.6-5. (c) Con
