 Material dispersion coefficient

The material dispersion coefficient is a key parameter in the field of optics and fiber optics that quantifies how much different wavelengths of light travel at different speeds through a material. This phenomenon occurs because the refractive index of a material changes with the wavelength of light, causing various wavelengths to experience different propagation velocities. In optical fibers, material dispersion contributes to pulse broadening as light pulses travel down the fiber.
